Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604528, here are decompositions:

19 + 31604509 = 31604528
31 + 31604497 = 31604528
157 + 31604371 = 31604528
181 + 31604347 = 31604528
229 + 31604299 = 31604528
337 + 31604191 = 31604528
541 + 31603987 = 31604528
727 + 31603801 = 31604528

Showing the first eight; more decompositions exist.
