Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604286, here are decompositions:

5 + 31604281 = 31604286
23 + 31604263 = 31604286
59 + 31604227 = 31604286
67 + 31604219 = 31604286
97 + 31604189 = 31604286
149 + 31604137 = 31604286
157 + 31604129 = 31604286
229 + 31604057 = 31604286

Showing the first eight; more decompositions exist.
