Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508858, here are decompositions:

11 + 508847 = 508858
17 + 508841 = 508858
41 + 508817 = 508858
47 + 508811 = 508858
59 + 508799 = 508858
131 + 508727 = 508858
149 + 508709 = 508858
197 + 508661 = 508858

Showing the first eight; more decompositions exist.
