Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604586, here are decompositions:

29 + 31604557 = 31604586
53 + 31604533 = 31604586
89 + 31604497 = 31604586
199 + 31604387 = 31604586
227 + 31604359 = 31604586
229 + 31604357 = 31604586
239 + 31604347 = 31604586
283 + 31604303 = 31604586

Showing the first eight; more decompositions exist.
