Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604764, here are decompositions:

5 + 31604759 = 31604764
17 + 31604747 = 31604764
41 + 31604723 = 31604764
83 + 31604681 = 31604764
137 + 31604627 = 31604764
263 + 31604501 = 31604764
311 + 31604453 = 31604764
461 + 31604303 = 31604764

Showing the first eight; more decompositions exist.
