Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022550, here are decompositions:

19 + 1022531 = 1022550
31 + 1022519 = 1022550
37 + 1022513 = 1022550
41 + 1022509 = 1022550
43 + 1022507 = 1022550
47 + 1022503 = 1022550
59 + 1022491 = 1022550
83 + 1022467 = 1022550

Showing the first eight; more decompositions exist.
