Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625804, here are decompositions:

31 + 31625773 = 31625804
37 + 31625767 = 31625804
43 + 31625761 = 31625804
73 + 31625731 = 31625804
151 + 31625653 = 31625804
157 + 31625647 = 31625804
241 + 31625563 = 31625804
337 + 31625467 = 31625804

Showing the first eight; more decompositions exist.
