Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943816, here are decompositions:

17 + 943799 = 943816
47 + 943769 = 943816
53 + 943763 = 943816
59 + 943757 = 943816
179 + 943637 = 943816
227 + 943589 = 943816
317 + 943499 = 943816
443 + 943373 = 943816

Showing the first eight; more decompositions exist.
