Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604304, here are decompositions:

5 + 31604299 = 31604304
7 + 31604297 = 31604304
23 + 31604281 = 31604304
41 + 31604263 = 31604304
113 + 31604191 = 31604304
167 + 31604137 = 31604304
271 + 31604033 = 31604304
313 + 31603991 = 31604304

Showing the first eight; more decompositions exist.
