Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022540, here are decompositions:

31 + 1022509 = 1022540
37 + 1022503 = 1022540
73 + 1022467 = 1022540
97 + 1022443 = 1022540
151 + 1022389 = 1022540
157 + 1022383 = 1022540
163 + 1022377 = 1022540
199 + 1022341 = 1022540

Showing the first eight; more decompositions exist.
