Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604784, here are decompositions:

17 + 31604767 = 31604784
37 + 31604747 = 31604784
41 + 31604743 = 31604784
53 + 31604731 = 31604784
61 + 31604723 = 31604784
97 + 31604687 = 31604784
103 + 31604681 = 31604784
137 + 31604647 = 31604784

Showing the first eight; more decompositions exist.
