Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518968, here are decompositions:

101 + 518867 = 518968
137 + 518831 = 518968
167 + 518801 = 518968
227 + 518741 = 518968
239 + 518729 = 518968
251 + 518717 = 518968
269 + 518699 = 518968
311 + 518657 = 518968

Showing the first eight; more decompositions exist.
