Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625114, here are decompositions:

163 + 31624951 = 31625114
193 + 31624921 = 31625114
277 + 31624837 = 31625114
307 + 31624807 = 31625114
331 + 31624783 = 31625114
373 + 31624741 = 31625114
397 + 31624717 = 31625114
487 + 31624627 = 31625114

Showing the first eight; more decompositions exist.
