Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604262, here are decompositions:

43 + 31604219 = 31604262
71 + 31604191 = 31604262
73 + 31604189 = 31604262
163 + 31604099 = 31604262
211 + 31604051 = 31604262
229 + 31604033 = 31604262
271 + 31603991 = 31604262
331 + 31603931 = 31604262

Showing the first eight; more decompositions exist.
