Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66268, here are decompositions:

29 + 66239 = 66268
47 + 66221 = 66268
89 + 66179 = 66268
107 + 66161 = 66268
131 + 66137 = 66268
179 + 66089 = 66268
197 + 66071 = 66268
227 + 66041 = 66268

Showing the first eight; more decompositions exist.
