Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607108, here are decompositions:

7 + 31607101 = 31607108
61 + 31607047 = 31607108
151 + 31606957 = 31607108
157 + 31606951 = 31607108
229 + 31606879 = 31607108
367 + 31606741 = 31607108
397 + 31606711 = 31607108
457 + 31606651 = 31607108

Showing the first eight; more decompositions exist.
