Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529304, here are decompositions:

31 + 31529273 = 31529304
47 + 31529257 = 31529304
61 + 31529243 = 31529304
137 + 31529167 = 31529304
197 + 31529107 = 31529304
223 + 31529081 = 31529304
251 + 31529053 = 31529304
307 + 31528997 = 31529304

Showing the first eight; more decompositions exist.
