Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66718, here are decompositions:

5 + 66713 = 66718
17 + 66701 = 66718
89 + 66629 = 66718
101 + 66617 = 66718
131 + 66587 = 66718
149 + 66569 = 66718
227 + 66491 = 66718
251 + 66467 = 66718

Showing the first eight; more decompositions exist.
