Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022456, here are decompositions:

7 + 1022449 = 1022456
13 + 1022443 = 1022456
67 + 1022389 = 1022456
73 + 1022383 = 1022456
79 + 1022377 = 1022456
277 + 1022179 = 1022456
373 + 1022083 = 1022456
397 + 1022059 = 1022456

Showing the first eight; more decompositions exist.
