Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604246, here are decompositions:

19 + 31604227 = 31604246
109 + 31604137 = 31604246
313 + 31603933 = 31604246
367 + 31603879 = 31604246
727 + 31603519 = 31604246
757 + 31603489 = 31604246
853 + 31603393 = 31604246
937 + 31603309 = 31604246

Showing the first eight; more decompositions exist.
