Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604066, here are decompositions:

79 + 31603987 = 31604066
223 + 31603843 = 31604066
349 + 31603717 = 31604066
409 + 31603657 = 31604066
457 + 31603609 = 31604066
499 + 31603567 = 31604066
547 + 31603519 = 31604066
577 + 31603489 = 31604066

Showing the first eight; more decompositions exist.
