Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022750, here are decompositions:

31 + 1022719 = 1022750
61 + 1022689 = 1022750
67 + 1022683 = 1022750
73 + 1022677 = 1022750
97 + 1022653 = 1022750
139 + 1022611 = 1022750
241 + 1022509 = 1022750
283 + 1022467 = 1022750

Showing the first eight; more decompositions exist.
