Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516822, here are decompositions:

11 + 516811 = 516822
29 + 516793 = 516822
101 + 516721 = 516822
109 + 516713 = 516822
113 + 516709 = 516822
149 + 516673 = 516822
179 + 516643 = 516822
199 + 516623 = 516822

Showing the first eight; more decompositions exist.
