Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501886, here are decompositions:

23 + 501863 = 501886
59 + 501827 = 501886
83 + 501803 = 501886
107 + 501779 = 501886
167 + 501719 = 501886
179 + 501707 = 501886
227 + 501659 = 501886
263 + 501623 = 501886

Showing the first eight; more decompositions exist.
