Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522748, here are decompositions:

11 + 522737 = 522748
29 + 522719 = 522748
41 + 522707 = 522748
59 + 522689 = 522748
71 + 522677 = 522748
89 + 522659 = 522748
179 + 522569 = 522748
227 + 522521 = 522748

Showing the first eight; more decompositions exist.
