Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516064, here are decompositions:

3 + 31516061 = 31516064
37 + 31516027 = 31516064
43 + 31516021 = 31516064
127 + 31515937 = 31516064
331 + 31515733 = 31516064
367 + 31515697 = 31516064
457 + 31515607 = 31516064
487 + 31515577 = 31516064

Showing the first eight; more decompositions exist.
