Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604270, here are decompositions:

7 + 31604263 = 31604270
43 + 31604227 = 31604270
79 + 31604191 = 31604270
283 + 31603987 = 31604270
337 + 31603933 = 31604270
613 + 31603657 = 31604270
661 + 31603609 = 31604270
751 + 31603519 = 31604270

Showing the first eight; more decompositions exist.
