Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604516, here are decompositions:

7 + 31604509 = 31604516
19 + 31604497 = 31604516
157 + 31604359 = 31604516
379 + 31604137 = 31604516
673 + 31603843 = 31604516
859 + 31603657 = 31604516
907 + 31603609 = 31604516
997 + 31603519 = 31604516

Showing the first eight; more decompositions exist.
