Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518998, here are decompositions:

17 + 518981 = 518998
131 + 518867 = 518998
167 + 518831 = 518998
191 + 518807 = 518998
197 + 518801 = 518998
239 + 518759 = 518998
251 + 518747 = 518998
257 + 518741 = 518998

Showing the first eight; more decompositions exist.
