Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022738, here are decompositions:

19 + 1022719 = 1022738
37 + 1022701 = 1022738
61 + 1022677 = 1022738
109 + 1022629 = 1022738
127 + 1022611 = 1022738
229 + 1022509 = 1022738
271 + 1022467 = 1022738
349 + 1022389 = 1022738

Showing the first eight; more decompositions exist.
