Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999816, here are decompositions:

7 + 999809 = 999816
43 + 999773 = 999816
47 + 999769 = 999816
53 + 999763 = 999816
67 + 999749 = 999816
89 + 999727 = 999816
149 + 999667 = 999816
163 + 999653 = 999816

Showing the first eight; more decompositions exist.
