Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66656, here are decompositions:

3 + 66653 = 66656
13 + 66643 = 66656
103 + 66553 = 66656
127 + 66529 = 66656
157 + 66499 = 66656
193 + 66463 = 66656
199 + 66457 = 66656
283 + 66373 = 66656

Showing the first eight; more decompositions exist.
