Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607916, here are decompositions:

7 + 31607909 = 31607916
13 + 31607903 = 31607916
19 + 31607897 = 31607916
47 + 31607869 = 31607916
59 + 31607857 = 31607916
127 + 31607789 = 31607916
199 + 31607717 = 31607916
227 + 31607689 = 31607916

Showing the first eight; more decompositions exist.
