Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625006, here are decompositions:

67 + 31624939 = 31625006
79 + 31624927 = 31625006
157 + 31624849 = 31625006
199 + 31624807 = 31625006
223 + 31624783 = 31625006
307 + 31624699 = 31625006
367 + 31624639 = 31625006
379 + 31624627 = 31625006

Showing the first eight; more decompositions exist.
