Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022636, here are decompositions:

3 + 1022633 = 1022636
7 + 1022629 = 1022636
127 + 1022509 = 1022636
193 + 1022443 = 1022636
457 + 1022179 = 1022636
499 + 1022137 = 1022636
523 + 1022113 = 1022636
577 + 1022059 = 1022636

Showing the first eight; more decompositions exist.
