Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625656, here are decompositions:

3 + 31625653 = 31625656
5 + 31625651 = 31625656
53 + 31625603 = 31625656
89 + 31625567 = 31625656
149 + 31625507 = 31625656
263 + 31625393 = 31625656
353 + 31625303 = 31625656
509 + 31625147 = 31625656

Showing the first eight; more decompositions exist.
