Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523108, here are decompositions:

157 + 31522951 = 31523108
439 + 31522669 = 31523108
751 + 31522357 = 31523108
769 + 31522339 = 31523108
811 + 31522297 = 31523108
1087 + 31522021 = 31523108
1117 + 31521991 = 31523108
1129 + 31521979 = 31523108

Showing the first eight; more decompositions exist.
