Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604806, here are decompositions:

3 + 31604803 = 31604806
17 + 31604789 = 31604806
47 + 31604759 = 31604806
59 + 31604747 = 31604806
83 + 31604723 = 31604806
179 + 31604627 = 31604806
197 + 31604609 = 31604806
353 + 31604453 = 31604806

Showing the first eight; more decompositions exist.
