Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022798, here are decompositions:

37 + 1022761 = 1022798
79 + 1022719 = 1022798
97 + 1022701 = 1022798
109 + 1022689 = 1022798
307 + 1022491 = 1022798
331 + 1022467 = 1022798
349 + 1022449 = 1022798
409 + 1022389 = 1022798

Showing the first eight; more decompositions exist.
