Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625084, here are decompositions:

157 + 31624927 = 31625084
163 + 31624921 = 31625084
223 + 31624861 = 31625084
277 + 31624807 = 31625084
331 + 31624753 = 31625084
367 + 31624717 = 31625084
457 + 31624627 = 31625084
487 + 31624597 = 31625084

Showing the first eight; more decompositions exist.
