Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16822, here are decompositions:

11 + 16811 = 16822
59 + 16763 = 16822
131 + 16691 = 16822
149 + 16673 = 16822
173 + 16649 = 16822
191 + 16631 = 16822
269 + 16553 = 16822
293 + 16529 = 16822

Showing the first eight; more decompositions exist.
