Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604036, here are decompositions:

3 + 31604033 = 31604036
103 + 31603933 = 31604036
157 + 31603879 = 31604036
193 + 31603843 = 31604036
379 + 31603657 = 31604036
547 + 31603489 = 31604036
643 + 31603393 = 31604036
727 + 31603309 = 31604036

Showing the first eight; more decompositions exist.
