Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624630, here are decompositions:

3 + 31624627 = 31624630
17 + 31624613 = 31624630
71 + 31624559 = 31624630
83 + 31624547 = 31624630
173 + 31624457 = 31624630
263 + 31624367 = 31624630
281 + 31624349 = 31624630
293 + 31624337 = 31624630

Showing the first eight; more decompositions exist.
