Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625296, here are decompositions:

149 + 31625147 = 31625296
239 + 31625057 = 31625296
257 + 31625039 = 31625296
317 + 31624979 = 31625296
389 + 31624907 = 31625296
467 + 31624829 = 31625296
557 + 31624739 = 31625296
653 + 31624643 = 31625296

Showing the first eight; more decompositions exist.
