Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022666, here are decompositions:

13 + 1022653 = 1022666
37 + 1022629 = 1022666
157 + 1022509 = 1022666
163 + 1022503 = 1022666
199 + 1022467 = 1022666
223 + 1022443 = 1022666
277 + 1022389 = 1022666
283 + 1022383 = 1022666

Showing the first eight; more decompositions exist.
