Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522786, here are decompositions:

23 + 522763 = 522786
29 + 522757 = 522786
37 + 522749 = 522786
67 + 522719 = 522786
79 + 522707 = 522786
83 + 522703 = 522786
97 + 522689 = 522786
107 + 522679 = 522786

Showing the first eight; more decompositions exist.
