Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604964, here are decompositions:

5 + 31604959 = 31604964
31 + 31604933 = 31604964
101 + 31604863 = 31604964
197 + 31604767 = 31604964
233 + 31604731 = 31604964
241 + 31604723 = 31604964
277 + 31604687 = 31604964
283 + 31604681 = 31604964

Showing the first eight; more decompositions exist.
