Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022538, here are decompositions:

7 + 1022531 = 1022538
19 + 1022519 = 1022538
29 + 1022509 = 1022538
31 + 1022507 = 1022538
37 + 1022501 = 1022538
47 + 1022491 = 1022538
71 + 1022467 = 1022538
89 + 1022449 = 1022538

Showing the first eight; more decompositions exist.
