Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604716, here are decompositions:

29 + 31604687 = 31604716
89 + 31604627 = 31604716
107 + 31604609 = 31604716
113 + 31604603 = 31604716
263 + 31604453 = 31604716
359 + 31604357 = 31604716
419 + 31604297 = 31604716
587 + 31604129 = 31604716

Showing the first eight; more decompositions exist.
