Please consider the (presumably infinite) Euler product over the twin primes:
$$ f(z) = \prod_{p\in\mathbb{P}}^{\infty} \Big( 1 - \frac{1}{(p(p+2))^ z} \Big) $$ (in which $p(p+2)$ is a divisor of $4((p-1)!+1) + p$ ).
The Euler Product is a product of a corresponding Dirichlet series. Which one is that?
Thanks in advance,
Max
