Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522806, here are decompositions:

19 + 522787 = 522806
43 + 522763 = 522806
103 + 522703 = 522806
127 + 522679 = 522806
283 + 522523 = 522806
337 + 522469 = 522806
367 + 522439 = 522806
397 + 522409 = 522806

Showing the first eight; more decompositions exist.
