Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529112, here are decompositions:

5 + 31529107 = 31529112
23 + 31529089 = 31529112
31 + 31529081 = 31529112
59 + 31529053 = 31529112
269 + 31528843 = 31529112
271 + 31528841 = 31529112
281 + 31528831 = 31529112
311 + 31528801 = 31529112

Showing the first eight; more decompositions exist.
