Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028816, here are decompositions:

7 + 1028809 = 1028816
13 + 1028803 = 1028816
43 + 1028773 = 1028816
67 + 1028749 = 1028816
79 + 1028737 = 1028816
199 + 1028617 = 1028816
307 + 1028509 = 1028816
337 + 1028479 = 1028816

Showing the first eight; more decompositions exist.
