Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522818, here are decompositions:

7 + 522811 = 522818
31 + 522787 = 522818
61 + 522757 = 522818
139 + 522679 = 522818
157 + 522661 = 522818
181 + 522637 = 522818
277 + 522541 = 522818
349 + 522469 = 522818

Showing the first eight; more decompositions exist.
