Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604302, here are decompositions:

3 + 31604299 = 31604302
5 + 31604297 = 31604302
83 + 31604219 = 31604302
113 + 31604189 = 31604302
173 + 31604129 = 31604302
251 + 31604051 = 31604302
269 + 31604033 = 31604302
311 + 31603991 = 31604302

Showing the first eight; more decompositions exist.
