Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604282, here are decompositions:

19 + 31604263 = 31604282
349 + 31603933 = 31604282
439 + 31603843 = 31604282
571 + 31603711 = 31604282
601 + 31603681 = 31604282
673 + 31603609 = 31604282
1021 + 31603261 = 31604282
1033 + 31603249 = 31604282

Showing the first eight; more decompositions exist.
