Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022448, here are decompositions:

5 + 1022443 = 1022448
19 + 1022429 = 1022448
59 + 1022389 = 1022448
61 + 1022387 = 1022448
67 + 1022381 = 1022448
71 + 1022377 = 1022448
107 + 1022341 = 1022448
157 + 1022291 = 1022448

Showing the first eight; more decompositions exist.
