Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022490, here are decompositions:

23 + 1022467 = 1022490
41 + 1022449 = 1022490
47 + 1022443 = 1022490
61 + 1022429 = 1022490
101 + 1022389 = 1022490
103 + 1022387 = 1022490
107 + 1022383 = 1022490
109 + 1022381 = 1022490

Showing the first eight; more decompositions exist.
