Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022720, here are decompositions:

19 + 1022701 = 1022720
31 + 1022689 = 1022720
37 + 1022683 = 1022720
43 + 1022677 = 1022720
67 + 1022653 = 1022720
109 + 1022611 = 1022720
211 + 1022509 = 1022720
229 + 1022491 = 1022720

Showing the first eight; more decompositions exist.
