Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604736, here are decompositions:

5 + 31604731 = 31604736
13 + 31604723 = 31604736
17 + 31604719 = 31604736
47 + 31604689 = 31604736
89 + 31604647 = 31604736
109 + 31604627 = 31604736
127 + 31604609 = 31604736
179 + 31604557 = 31604736

Showing the first eight; more decompositions exist.
