Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000816, here are decompositions:

23 + 1000793 = 1000816
53 + 1000763 = 1000816
137 + 1000679 = 1000816
149 + 1000667 = 1000816
197 + 1000619 = 1000816
227 + 1000589 = 1000816
239 + 1000577 = 1000816
269 + 1000547 = 1000816

Showing the first eight; more decompositions exist.
