Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518938, here are decompositions:

5 + 518933 = 518938
71 + 518867 = 518938
107 + 518831 = 518938
131 + 518807 = 518938
137 + 518801 = 518938
179 + 518759 = 518938
191 + 518747 = 518938
197 + 518741 = 518938

Showing the first eight; more decompositions exist.
