Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604250, here are decompositions:

23 + 31604227 = 31604250
31 + 31604219 = 31604250
59 + 31604191 = 31604250
61 + 31604189 = 31604250
113 + 31604137 = 31604250
151 + 31604099 = 31604250
193 + 31604057 = 31604250
199 + 31604051 = 31604250

Showing the first eight; more decompositions exist.
