Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625908, here are decompositions:

59 + 31625849 = 31625908
89 + 31625819 = 31625908
101 + 31625807 = 31625908
131 + 31625777 = 31625908
227 + 31625681 = 31625908
257 + 31625651 = 31625908
401 + 31625507 = 31625908
557 + 31625351 = 31625908

Showing the first eight; more decompositions exist.
