Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66650, here are decompositions:

7 + 66643 = 66650
79 + 66571 = 66650
97 + 66553 = 66650
109 + 66541 = 66650
127 + 66523 = 66650
151 + 66499 = 66650
193 + 66457 = 66650
277 + 66373 = 66650

Showing the first eight; more decompositions exist.
