Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522726, here are decompositions:

7 + 522719 = 522726
19 + 522707 = 522726
23 + 522703 = 522726
37 + 522689 = 522726
47 + 522679 = 522726
53 + 522673 = 522726
67 + 522659 = 522726
89 + 522637 = 522726

Showing the first eight; more decompositions exist.
