Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518944, here are decompositions:

11 + 518933 = 518944
113 + 518831 = 518944
131 + 518813 = 518944
137 + 518807 = 518944
197 + 518747 = 518944
227 + 518717 = 518944
347 + 518597 = 518944
401 + 518543 = 518944

Showing the first eight; more decompositions exist.
