Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520858, here are decompositions:

5 + 520853 = 520858
17 + 520841 = 520858
71 + 520787 = 520858
137 + 520721 = 520858
167 + 520691 = 520858
179 + 520679 = 520858
227 + 520631 = 520858
251 + 520607 = 520858

Showing the first eight; more decompositions exist.
