Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607804, here are decompositions:

13 + 31607791 = 31607804
223 + 31607581 = 31607804
331 + 31607473 = 31607804
463 + 31607341 = 31607804
523 + 31607281 = 31607804
541 + 31607263 = 31607804
577 + 31607227 = 31607804
757 + 31607047 = 31607804

Showing the first eight; more decompositions exist.
