Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604486, here are decompositions:

103 + 31604383 = 31604486
127 + 31604359 = 31604486
139 + 31604347 = 31604486
223 + 31604263 = 31604486
349 + 31604137 = 31604486
499 + 31603987 = 31604486
607 + 31603879 = 31604486
643 + 31603843 = 31604486

Showing the first eight; more decompositions exist.
