Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66280, here are decompositions:

41 + 66239 = 66280
59 + 66221 = 66280
89 + 66191 = 66280
101 + 66179 = 66280
107 + 66173 = 66280
173 + 66107 = 66280
191 + 66089 = 66280
197 + 66083 = 66280

Showing the first eight; more decompositions exist.
