Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604798, here are decompositions:

31 + 31604767 = 31604798
67 + 31604731 = 31604798
79 + 31604719 = 31604798
109 + 31604689 = 31604798
151 + 31604647 = 31604798
157 + 31604641 = 31604798
241 + 31604557 = 31604798
439 + 31604359 = 31604798

Showing the first eight; more decompositions exist.
