Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66610, here are decompositions:

17 + 66593 = 66610
23 + 66587 = 66610
41 + 66569 = 66610
101 + 66509 = 66610
179 + 66431 = 66610
197 + 66413 = 66610
227 + 66383 = 66610
233 + 66377 = 66610

Showing the first eight; more decompositions exist.
