Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66310, here are decompositions:

17 + 66293 = 66310
71 + 66239 = 66310
89 + 66221 = 66310
131 + 66179 = 66310
137 + 66173 = 66310
149 + 66161 = 66310
173 + 66137 = 66310
227 + 66083 = 66310

Showing the first eight; more decompositions exist.
