摘要:
Let N be a sufficiently large integer. In this paper, it is proved that, with at most O(N119/270+c) exceptions, all even positive integers up to N can be represented in the form p(1)(2) + p(2)(2) + p(3)(3) + p(4)(3) + p(5)(6) + p(6) (6), where p(1), p(2), p(3), p(4), p(5), p(6) are prime numbers.
