Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042816, here are decompositions:

17 + 1042799 = 1042816
83 + 1042733 = 1042816
107 + 1042709 = 1042816
113 + 1042703 = 1042816
197 + 1042619 = 1042816
233 + 1042583 = 1042816
239 + 1042577 = 1042816
293 + 1042523 = 1042816

Showing the first eight; more decompositions exist.
