Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604922, here are decompositions:

59 + 31604863 = 31604922
73 + 31604849 = 31604922
163 + 31604759 = 31604922
179 + 31604743 = 31604922
191 + 31604731 = 31604922
199 + 31604723 = 31604922
233 + 31604689 = 31604922
241 + 31604681 = 31604922

Showing the first eight; more decompositions exist.
