Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516108, here are decompositions:

5 + 31516103 = 31516108
47 + 31516061 = 31516108
101 + 31516007 = 31516108
167 + 31515941 = 31516108
227 + 31515881 = 31516108
251 + 31515857 = 31516108
389 + 31515719 = 31516108
431 + 31515677 = 31516108

Showing the first eight; more decompositions exist.
