Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66228, here are decompositions:

7 + 66221 = 66228
37 + 66191 = 66228
59 + 66169 = 66228
67 + 66161 = 66228
139 + 66089 = 66228
157 + 66071 = 66228
181 + 66047 = 66228
191 + 66037 = 66228

Showing the first eight; more decompositions exist.
