Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604874, here are decompositions:

11 + 31604863 = 31604874
71 + 31604803 = 31604874
107 + 31604767 = 31604874
127 + 31604747 = 31604874
131 + 31604743 = 31604874
151 + 31604723 = 31604874
193 + 31604681 = 31604874
227 + 31604647 = 31604874

Showing the first eight; more decompositions exist.
