Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66466, here are decompositions:

3 + 66463 = 66466
17 + 66449 = 66466
53 + 66413 = 66466
83 + 66383 = 66466
89 + 66377 = 66466
107 + 66359 = 66466
173 + 66293 = 66466
227 + 66239 = 66466

Showing the first eight; more decompositions exist.
