Is this a valid function for number of prime pairs for n=2p and p is prime and n gets large?

For even integer n=2p where p is a prime number, as n gets large, does the number of prime pairs P(n) approaches the following equation:



$P(n) = (frac{n}{2})(1-2W(l(sqrt n))$



where l(√n) is the largest prime number less than √n, and W(x) is defined as the following function:



$W(x) = sum_{p=3}^{x} frac{1}{p}left(prod_{q=3}^{l(p)} frac{(q-2)}{q}right)$



where the sum and products are over prime numbers and x is a prime number.



A prime pair of n is a pair (p1,p2) such that p1 and p2 are prime and p1+p2=n.
