Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022838, here are decompositions:

17 + 1022821 = 1022838
41 + 1022797 = 1022838
109 + 1022729 = 1022838
137 + 1022701 = 1022838
149 + 1022689 = 1022838
199 + 1022639 = 1022838
227 + 1022611 = 1022838
307 + 1022531 = 1022838

Showing the first eight; more decompositions exist.
