Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604766, here are decompositions:

7 + 31604759 = 31604766
19 + 31604747 = 31604766
23 + 31604743 = 31604766
43 + 31604723 = 31604766
47 + 31604719 = 31604766
79 + 31604687 = 31604766
139 + 31604627 = 31604766
157 + 31604609 = 31604766

Showing the first eight; more decompositions exist.
