Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529118, here are decompositions:

11 + 31529107 = 31529118
29 + 31529089 = 31529118
31 + 31529087 = 31529118
37 + 31529081 = 31529118
149 + 31528969 = 31529118
151 + 31528967 = 31529118
277 + 31528841 = 31529118
307 + 31528811 = 31529118

Showing the first eight; more decompositions exist.
