Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66406, here are decompositions:

3 + 66403 = 66406
23 + 66383 = 66406
29 + 66377 = 66406
47 + 66359 = 66406
59 + 66347 = 66406
113 + 66293 = 66406
167 + 66239 = 66406
227 + 66179 = 66406

Showing the first eight; more decompositions exist.
