Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625966, here are decompositions:

3 + 31625963 = 31625966
13 + 31625953 = 31625966
193 + 31625773 = 31625966
199 + 31625767 = 31625966
313 + 31625653 = 31625966
349 + 31625617 = 31625966
367 + 31625599 = 31625966
457 + 31625509 = 31625966

Showing the first eight; more decompositions exist.
