Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66618, here are decompositions:

17 + 66601 = 66618
31 + 66587 = 66618
47 + 66571 = 66618
89 + 66529 = 66618
109 + 66509 = 66618
127 + 66491 = 66618
151 + 66467 = 66618
241 + 66377 = 66618

Showing the first eight; more decompositions exist.
