Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604930, here are decompositions:

67 + 31604863 = 31604930
127 + 31604803 = 31604930
163 + 31604767 = 31604930
199 + 31604731 = 31604930
211 + 31604719 = 31604930
241 + 31604689 = 31604930
283 + 31604647 = 31604930
373 + 31604557 = 31604930

Showing the first eight; more decompositions exist.
