Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604976, here are decompositions:

17 + 31604959 = 31604976
43 + 31604933 = 31604976
113 + 31604863 = 31604976
127 + 31604849 = 31604976
173 + 31604803 = 31604976
229 + 31604747 = 31604976
233 + 31604743 = 31604976
257 + 31604719 = 31604976

Showing the first eight; more decompositions exist.
