Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604494, here are decompositions:

41 + 31604453 = 31604494
107 + 31604387 = 31604494
137 + 31604357 = 31604494
191 + 31604303 = 31604494
197 + 31604297 = 31604494
443 + 31604051 = 31604494
461 + 31604033 = 31604494
503 + 31603991 = 31604494

Showing the first eight; more decompositions exist.
