Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66676, here are decompositions:

23 + 66653 = 66676
47 + 66629 = 66676
59 + 66617 = 66676
83 + 66593 = 66676
89 + 66587 = 66676
107 + 66569 = 66676
167 + 66509 = 66676
227 + 66449 = 66676

Showing the first eight; more decompositions exist.
