Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604230, here are decompositions:

3 + 31604227 = 31604230
11 + 31604219 = 31604230
41 + 31604189 = 31604230
101 + 31604129 = 31604230
131 + 31604099 = 31604230
173 + 31604057 = 31604230
179 + 31604051 = 31604230
197 + 31604033 = 31604230

Showing the first eight; more decompositions exist.
