Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604536, here are decompositions:

3 + 31604533 = 31604536
83 + 31604453 = 31604536
149 + 31604387 = 31604536
179 + 31604357 = 31604536
233 + 31604303 = 31604536
239 + 31604297 = 31604536
317 + 31604219 = 31604536
347 + 31604189 = 31604536

Showing the first eight; more decompositions exist.
