Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604816, here are decompositions:

13 + 31604803 = 31604816
73 + 31604743 = 31604816
97 + 31604719 = 31604816
127 + 31604689 = 31604816
283 + 31604533 = 31604816
307 + 31604509 = 31604816
433 + 31604383 = 31604816
457 + 31604359 = 31604816

Showing the first eight; more decompositions exist.
