Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625512, here are decompositions:

3 + 31625509 = 31625512
5 + 31625507 = 31625512
59 + 31625453 = 31625512
101 + 31625411 = 31625512
131 + 31625381 = 31625512
251 + 31625261 = 31625512
683 + 31624829 = 31625512
773 + 31624739 = 31625512

Showing the first eight; more decompositions exist.
