Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022486, here are decompositions:

19 + 1022467 = 1022486
37 + 1022449 = 1022486
43 + 1022443 = 1022486
97 + 1022389 = 1022486
103 + 1022383 = 1022486
109 + 1022377 = 1022486
277 + 1022209 = 1022486
307 + 1022179 = 1022486

Showing the first eight; more decompositions exist.
