Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66722, here are decompositions:

79 + 66643 = 66722
151 + 66571 = 66722
181 + 66541 = 66722
193 + 66529 = 66722
199 + 66523 = 66722
223 + 66499 = 66722
349 + 66373 = 66722
379 + 66343 = 66722

Showing the first eight; more decompositions exist.
