Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567016, here are decompositions:

37 + 31566979 = 31567016
43 + 31566973 = 31567016
97 + 31566919 = 31567016
199 + 31566817 = 31567016
223 + 31566793 = 31567016
307 + 31566709 = 31567016
457 + 31566559 = 31567016
499 + 31566517 = 31567016

Showing the first eight; more decompositions exist.
