Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625608, here are decompositions:

5 + 31625603 = 31625608
29 + 31625579 = 31625608
41 + 31625567 = 31625608
71 + 31625537 = 31625608
101 + 31625507 = 31625608
197 + 31625411 = 31625608
227 + 31625381 = 31625608
257 + 31625351 = 31625608

Showing the first eight; more decompositions exist.
