Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604308, here are decompositions:

5 + 31604303 = 31604308
11 + 31604297 = 31604308
89 + 31604219 = 31604308
179 + 31604129 = 31604308
251 + 31604057 = 31604308
257 + 31604051 = 31604308
317 + 31603991 = 31604308
389 + 31603919 = 31604308

Showing the first eight; more decompositions exist.
