Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66448, here are decompositions:

17 + 66431 = 66448
71 + 66377 = 66448
89 + 66359 = 66448
101 + 66347 = 66448
227 + 66221 = 66448
257 + 66191 = 66448
269 + 66179 = 66448
311 + 66137 = 66448

Showing the first eight; more decompositions exist.
