Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604674, here are decompositions:

47 + 31604627 = 31604674
71 + 31604603 = 31604674
113 + 31604561 = 31604674
173 + 31604501 = 31604674
317 + 31604357 = 31604674
617 + 31604057 = 31604674
641 + 31604033 = 31604674
683 + 31603991 = 31604674

Showing the first eight; more decompositions exist.
