Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022816, here are decompositions:

19 + 1022797 = 1022816
43 + 1022773 = 1022816
97 + 1022719 = 1022816
127 + 1022689 = 1022816
139 + 1022677 = 1022816
163 + 1022653 = 1022816
307 + 1022509 = 1022816
313 + 1022503 = 1022816

Showing the first eight; more decompositions exist.
