Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66764, here are decompositions:

13 + 66751 = 66764
31 + 66733 = 66764
43 + 66721 = 66764
67 + 66697 = 66764
163 + 66601 = 66764
193 + 66571 = 66764
211 + 66553 = 66764
223 + 66541 = 66764

Showing the first eight; more decompositions exist.
