## A Sieve for the Twin Primes

**Authors:** H. L. Mitchell

This paper presents a sieve for the twin primes using a double application of the Sieve of Eratosthenes to the k index for multiples of 6 centered around the primes ranging from 5 to sqrt N. Considering the set {(6k-1, 6k+1)}, we look at the exact pattern in which multiples of primes p occur in the set with respect to the values of k. By deleting the values of k such that 6k-1 is composite, we get the set of all pairs such that 6k-1 is prime, then from these we delete those in which 6k+1 is composite. That leaves us with the set of all twin primes less than N.
We derive a mathematical formula accordingly using the Euler product formula, the Prime
Number Theorem, Mertens’ Theorem and the Hardy-Littlewood Conjecture.
The main results are:
1) A sieve for the twin primes similar to the sieve of Eratosthenes for primes
2) A formula for the approximate number of twin primes less than N in terms of the number of
primes
3) The asymptotic formula for the number of twin primes less than N
