Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518950, here are decompositions:

17 + 518933 = 518950
83 + 518867 = 518950
137 + 518813 = 518950
149 + 518801 = 518950
191 + 518759 = 518950
233 + 518717 = 518950
251 + 518699 = 518950
293 + 518657 = 518950

Showing the first eight; more decompositions exist.
