Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66620, here are decompositions:

3 + 66617 = 66620
19 + 66601 = 66620
67 + 66553 = 66620
79 + 66541 = 66620
97 + 66523 = 66620
157 + 66463 = 66620
163 + 66457 = 66620
277 + 66343 = 66620

Showing the first eight; more decompositions exist.
