Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518980, here are decompositions:

47 + 518933 = 518980
113 + 518867 = 518980
149 + 518831 = 518980
167 + 518813 = 518980
173 + 518807 = 518980
179 + 518801 = 518980
233 + 518747 = 518980
239 + 518741 = 518980

Showing the first eight; more decompositions exist.
