Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604658, here are decompositions:

11 + 31604647 = 31604658
17 + 31604641 = 31604658
31 + 31604627 = 31604658
47 + 31604611 = 31604658
97 + 31604561 = 31604658
101 + 31604557 = 31604658
149 + 31604509 = 31604658
157 + 31604501 = 31604658

Showing the first eight; more decompositions exist.
