Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604502, here are decompositions:

5 + 31604497 = 31604502
131 + 31604371 = 31604502
191 + 31604311 = 31604502
199 + 31604303 = 31604502
239 + 31604263 = 31604502
283 + 31604219 = 31604502
311 + 31604191 = 31604502
313 + 31604189 = 31604502

Showing the first eight; more decompositions exist.
