Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607684, here are decompositions:

13 + 31607671 = 31607684
103 + 31607581 = 31607684
181 + 31607503 = 31607684
211 + 31607473 = 31607684
223 + 31607461 = 31607684
421 + 31607263 = 31607684
457 + 31607227 = 31607684
547 + 31607137 = 31607684

Showing the first eight; more decompositions exist.
