Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604234, here are decompositions:

7 + 31604227 = 31604234
43 + 31604191 = 31604234
97 + 31604137 = 31604234
433 + 31603801 = 31604234
523 + 31603711 = 31604234
577 + 31603657 = 31604234
853 + 31603381 = 31604234
1087 + 31603147 = 31604234

Showing the first eight; more decompositions exist.
