Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604464, here are decompositions:

11 + 31604453 = 31604464
107 + 31604357 = 31604464
167 + 31604297 = 31604464
431 + 31604033 = 31604464
587 + 31603877 = 31604464
743 + 31603721 = 31604464
821 + 31603643 = 31604464
887 + 31603577 = 31604464

Showing the first eight; more decompositions exist.
