Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510858, here are decompositions:

11 + 510847 = 510858
31 + 510827 = 510858
41 + 510817 = 510858
107 + 510751 = 510858
149 + 510709 = 510858
151 + 510707 = 510858
167 + 510691 = 510858
181 + 510677 = 510858

Showing the first eight; more decompositions exist.
