Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624898, here are decompositions:

37 + 31624861 = 31624898
61 + 31624837 = 31624898
157 + 31624741 = 31624898
181 + 31624717 = 31624898
199 + 31624699 = 31624898
271 + 31624627 = 31624898
307 + 31624591 = 31624898
421 + 31624477 = 31624898

Showing the first eight; more decompositions exist.
