Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625994, here are decompositions:

7 + 31625987 = 31625994
13 + 31625981 = 31625994
31 + 31625963 = 31625994
41 + 31625953 = 31625994
83 + 31625911 = 31625994
151 + 31625843 = 31625994
173 + 31625821 = 31625994
227 + 31625767 = 31625994

Showing the first eight; more decompositions exist.
