Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022688, here are decompositions:

5 + 1022683 = 1022688
11 + 1022677 = 1022688
59 + 1022629 = 1022688
97 + 1022591 = 1022688
157 + 1022531 = 1022688
179 + 1022509 = 1022688
181 + 1022507 = 1022688
197 + 1022491 = 1022688

Showing the first eight; more decompositions exist.
