Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625798, here are decompositions:

19 + 31625779 = 31625798
31 + 31625767 = 31625798
37 + 31625761 = 31625798
67 + 31625731 = 31625798
151 + 31625647 = 31625798
181 + 31625617 = 31625798
199 + 31625599 = 31625798
331 + 31625467 = 31625798

Showing the first eight; more decompositions exist.
