Chen's double sieve, Goldbach's conjecture and the twin prime problem, 2DOI: 10.4064/aa131-4-5 Abstract: For every even integer N, denote by D_{1,2}(N) the number of representations of N as a sum of a prime and an integer having at most two prime factors. In this paper, we give a new lower bound for D_{1,2}(N).
