Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604498, here are decompositions:

127 + 31604371 = 31604498
139 + 31604359 = 31604498
151 + 31604347 = 31604498
157 + 31604341 = 31604498
199 + 31604299 = 31604498
271 + 31604227 = 31604498
307 + 31604191 = 31604498
619 + 31603879 = 31604498

Showing the first eight; more decompositions exist.
