Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022918, here are decompositions:

7 + 1022911 = 1022918
19 + 1022899 = 1022918
37 + 1022881 = 1022918
97 + 1022821 = 1022918
157 + 1022761 = 1022918
199 + 1022719 = 1022918
229 + 1022689 = 1022918
241 + 1022677 = 1022918

Showing the first eight; more decompositions exist.
