Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604588, here are decompositions:

31 + 31604557 = 31604588
79 + 31604509 = 31604588
229 + 31604359 = 31604588
241 + 31604347 = 31604588
277 + 31604311 = 31604588
307 + 31604281 = 31604588
397 + 31604191 = 31604588
601 + 31603987 = 31604588

Showing the first eight; more decompositions exist.
