Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022528, here are decompositions:

19 + 1022509 = 1022528
37 + 1022491 = 1022528
61 + 1022467 = 1022528
79 + 1022449 = 1022528
139 + 1022389 = 1022528
151 + 1022377 = 1022528
277 + 1022251 = 1022528
337 + 1022191 = 1022528

Showing the first eight; more decompositions exist.
