Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522868, here are decompositions:

11 + 522857 = 522868
29 + 522839 = 522868
41 + 522827 = 522868
107 + 522761 = 522868
131 + 522737 = 522868
149 + 522719 = 522868
179 + 522689 = 522868
191 + 522677 = 522868

Showing the first eight; more decompositions exist.
