Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604838, here are decompositions:

71 + 31604767 = 31604838
79 + 31604759 = 31604838
107 + 31604731 = 31604838
149 + 31604689 = 31604838
151 + 31604687 = 31604838
157 + 31604681 = 31604838
191 + 31604647 = 31604838
197 + 31604641 = 31604838

Showing the first eight; more decompositions exist.
