Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66238, here are decompositions:

17 + 66221 = 66238
47 + 66191 = 66238
59 + 66179 = 66238
101 + 66137 = 66238
131 + 66107 = 66238
149 + 66089 = 66238
167 + 66071 = 66238
191 + 66047 = 66238

Showing the first eight; more decompositions exist.
