Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625764, here are decompositions:

3 + 31625761 = 31625764
11 + 31625753 = 31625764
41 + 31625723 = 31625764
83 + 31625681 = 31625764
113 + 31625651 = 31625764
197 + 31625567 = 31625764
227 + 31625537 = 31625764
257 + 31625507 = 31625764

Showing the first eight; more decompositions exist.
