This paper have proved a conjecture about that every even number is equal to the difference of two prime numbers by using a two-dimension sieve method of using odd composites to the difference formula...
It is conjectured that every integer N > 454 is the sum of seven nonnegative cubes. We prove the conjecture when N ≡ 2 mod 4. This result, together with a recent proof for 4|N,shows that the conjectur...
