Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604156, here are decompositions:

19 + 31604137 = 31604156
223 + 31603933 = 31604156
277 + 31603879 = 31604156
313 + 31603843 = 31604156
439 + 31603717 = 31604156
499 + 31603657 = 31604156
547 + 31603609 = 31604156
907 + 31603249 = 31604156

Showing the first eight; more decompositions exist.
