Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66806, here are decompositions:

43 + 66763 = 66806
67 + 66739 = 66806
73 + 66733 = 66806
109 + 66697 = 66806
163 + 66643 = 66806
277 + 66529 = 66806
283 + 66523 = 66806
307 + 66499 = 66806

Showing the first eight; more decompositions exist.
