Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602258, here are decompositions:

7 + 31602251 = 31602258
19 + 31602239 = 31602258
31 + 31602227 = 31602258
41 + 31602217 = 31602258
137 + 31602121 = 31602258
179 + 31602079 = 31602258
241 + 31602017 = 31602258
271 + 31601987 = 31602258

Showing the first eight; more decompositions exist.
