Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022808, here are decompositions:

11 + 1022797 = 1022808
47 + 1022761 = 1022808
79 + 1022729 = 1022808
89 + 1022719 = 1022808
107 + 1022701 = 1022808
131 + 1022677 = 1022808
179 + 1022629 = 1022808
197 + 1022611 = 1022808

Showing the first eight; more decompositions exist.
