Holy gravy. How'd you do that? Figure out this example, I mean.
Part of the problem here is that by using the infinite product of all primes, you're trying to make a statement about the divisibility of infinity that will not make sense like it would for the divisibility of a set of integers generated by the finite versions of your numerator functions (+-).The residue for all Primes >= 5 is +4,+2,-2, and -4, therefore any Prime >= 5, in the set of Primes, cannot divide the four elements of the two twin pairs.
Holy gravy. How'd you do that? Figure out this example, I mean.
True. Note however that it is not divisible by your set of primes.
This is why I take it to the set of all primes.
Its period is parallel to the sequence of primes up to that point (not divergent, not convergent).
What that means is that for I*P, it is prime at 1P (ie a series can be referenced from any point).
The equation shows the relationship between the set of primes and the set of integers at the 1/2 of the period. It does not matter how many primes are in the set, as no primes (2,3,>=5) in the set can divide parallel infinite series of odd primes....

Hi 1,618033
Not sure what the red progression is, but it could form in a slight variation a nice right angle with the -x and x in the Phi-related points.

There are exactly 30 possible numbers you can make by combining the residue of 2,3, and 5. Then the pattern will repeat, 0*30,1*30,2*30,...,I*30.

Is residue a specific mathematical term?
I'm wondering that if given an arbitrary positive integer M, you could find a mapping g: Z+ -> Z+ and use g(M) to bound the index of your product so that you would only need to consider a finite set of primes, perhaps {Pn: Pn <= (g(M))^(1/2)}, and try to show that there is a twin prime pair a, a+2 such that M < a < a +2 < g(M) using your approach.The equation shows the relationship between the set of primes and the set of integers at the 1/2 of the period. It does not matter how many primes are in the set, as no primes (2,3,>=5) in the set can divide parallel infinite series of odd primes.

There are three indivisible pairs (30+-1,30/2+-3+-1).
Spoiler :[note] these do not have to be prime themselves as we do not know at what point in the series we are. Also, the pairs at the 1/2 are not directly related to the pair at the period of repetition.
How many indivisible integers across more primes? prod_(n=0)^x{P[n]-1}
At period 2*3 we have two 1/2 pairs, slide to -1 and you have -1 and +1.
Slide to 7 and you have 5 and 7.
So how many twin pairs can be divided?
Consider a vertical stack of twin pairs.
101
101
101

101 5 divides one and only one column of 1s every 5th row, corrupting only two pairs.
Each prime can only eliminate 2/P indivisible pairs.

This means the number of indivisible pairs (each a parallel infinite series with a 1P point) is continuously growing even as they are spread thinner and thinner.

Total pairs indivisible by set of x primes? prod_(n=0)^x{P[n]-2}
It is late and I have gotten wordy ...
This is how the term residue is used in number theory.Is residue a specific mathematical term? Is it just the remainder after a modulus process?
...
Because every single number (except 1) will have a residue of zero for at least one prime, as you have included all primes. Therefore when you multiply the columns vertically, each column will have at least one zero, and the product will be zero. So that clearly won't leave any other indivisible integers, much less any pairs.
This is incorrect. We are dealing with integers, and 39215/2 is not an integer.Given the primes 5, 11, 23, 31, you'll get a pattern that repeats with period 39215.

^Don't know what role Pi is presented as playing there, but if you indeed have a practical equation which has Pi as its limit, then you might be interested in using this with it:

Besides, in that spiral you have only right-angled triangles to deal with, and all of the hypothenuses are square roots of integers. If i personally ever tried to examine phi and pi, along with a link between them, i would use such geometrical shapes since they appear more direct to work with.
None of that proves or disproves the twin prime conjecture. It just shows that P0,..., Pn does not divide P0*...*Pn*(2*I+-1)/2 +-1+-3 for arbitrarily large n. In the infinite case, none of those expressions are integers , and we're probably looking at {INFINITY, INFINITY, INFINITY, INFINITY} @ . In a finite case, it's not proven that out of {prod -4, prod -2, prod +2, prod +4) there must be 2 consecutive odd integers which are both prime, and not just relatively prime to P0,...,Pn.Consider:
How many P and PnP between (P[x]^2) and (P[x+1]^2)-1?
... the -1 is due to 2, (-1^2)=1,(2^2)-1=3
So,
... from 1..3 = [2,3]
... from 4..8 = [5,7] (we could switch to (P[x+1]^2)-2 from here on, if we wanted)
... from 9..24 = [11,13,17,19,23]
... from 25..48 = [29,31,37,41,43,47]
... etc, etc
Can 2 divide {ODD-4,ODD-2,ODD+2,ODD+4)? No.
Can 3 divide {3*I-4,3*I-2,3*I+2,3*I+4}? No.
Can P>=5 divide {P*I-4,P*I-2,P*I+2,P*I+4}? No.
Can any combination of ODD Primes (basically 2^x combos) divide {product+-3+-1}? Depending on the bounds of the product, unknown.
If it is true for all the subsets, it is true for the whole set.
This is incorrect. We are dealing with integers, and 39215/2 is not an integer.Rather, consider that sequence to be 5*11*23*31*i^2,5*11*23*31*i^4,3*5*11*23*31*i^4.
The period is 2*39215 and 39215 is at the 1/2.
This means that no prime in the set {5,11,23,31} can divide 39215+-3+-1 (39211,39213,39217,39219).
RE: infinite primes, period one, and subsequent pattern
If it is true for all subsets it is true for the whole set.
If my use of infinity seems confusing to you, replace both infinitys with variable b and examine results of b from 0 to infinity. {P[0]=2,P[1]=3,P[2]=5,etc}.
