Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66258, here are decompositions:

19 + 66239 = 66258
37 + 66221 = 66258
67 + 66191 = 66258
79 + 66179 = 66258
89 + 66169 = 66258
97 + 66161 = 66258
149 + 66109 = 66258
151 + 66107 = 66258

Showing the first eight; more decompositions exist.
