Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518922, here are decompositions:

11 + 518911 = 518922
29 + 518893 = 518922
59 + 518863 = 518922
109 + 518813 = 518922
113 + 518809 = 518922
163 + 518759 = 518922
179 + 518743 = 518922
181 + 518741 = 518922

Showing the first eight; more decompositions exist.
