Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604590, here are decompositions:

29 + 31604561 = 31604590
89 + 31604501 = 31604590
137 + 31604453 = 31604590
233 + 31604357 = 31604590
293 + 31604297 = 31604590
401 + 31604189 = 31604590
461 + 31604129 = 31604590
491 + 31604099 = 31604590

Showing the first eight; more decompositions exist.
