Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006816, here are decompositions:

17 + 1006799 = 1006816
47 + 1006769 = 1006816
179 + 1006637 = 1006816
227 + 1006589 = 1006816
233 + 1006583 = 1006816
257 + 1006559 = 1006816
269 + 1006547 = 1006816
347 + 1006469 = 1006816

Showing the first eight; more decompositions exist.
