Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022628, here are decompositions:

17 + 1022611 = 1022628
37 + 1022591 = 1022628
97 + 1022531 = 1022628
109 + 1022519 = 1022628
127 + 1022501 = 1022628
137 + 1022491 = 1022628
179 + 1022449 = 1022628
199 + 1022429 = 1022628

Showing the first eight; more decompositions exist.
