Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66454, here are decompositions:

5 + 66449 = 66454
23 + 66431 = 66454
41 + 66413 = 66454
71 + 66383 = 66454
107 + 66347 = 66454
233 + 66221 = 66454
263 + 66191 = 66454
281 + 66173 = 66454

Showing the first eight; more decompositions exist.
