Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604968, here are decompositions:

179 + 31604789 = 31604968
281 + 31604687 = 31604968
359 + 31604609 = 31604968
467 + 31604501 = 31604968
839 + 31604129 = 31604968
911 + 31604057 = 31604968
977 + 31603991 = 31604968
1049 + 31603919 = 31604968

Showing the first eight; more decompositions exist.
