Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66264, here are decompositions:

43 + 66221 = 66264
73 + 66191 = 66264
103 + 66161 = 66264
127 + 66137 = 66264
157 + 66107 = 66264
181 + 66083 = 66264
193 + 66071 = 66264
197 + 66067 = 66264

Showing the first eight; more decompositions exist.
