Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66502, here are decompositions:

3 + 66499 = 66502
11 + 66491 = 66502
53 + 66449 = 66502
71 + 66431 = 66502
89 + 66413 = 66502
263 + 66239 = 66502
281 + 66221 = 66502
311 + 66191 = 66502

Showing the first eight; more decompositions exist.
