Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518956, here are decompositions:

3 + 518953 = 518956
23 + 518933 = 518956
89 + 518867 = 518956
149 + 518807 = 518956
197 + 518759 = 518956
227 + 518729 = 518956
239 + 518717 = 518956
257 + 518699 = 518956

Showing the first eight; more decompositions exist.
