Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604288, here are decompositions:

7 + 31604281 = 31604288
61 + 31604227 = 31604288
97 + 31604191 = 31604288
151 + 31604137 = 31604288
409 + 31603879 = 31604288
487 + 31603801 = 31604288
571 + 31603717 = 31604288
577 + 31603711 = 31604288

Showing the first eight; more decompositions exist.
