Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519028, here are decompositions:

17 + 519011 = 519028
47 + 518981 = 519028
197 + 518831 = 519028
227 + 518801 = 519028
269 + 518759 = 519028
281 + 518747 = 519028
311 + 518717 = 519028
431 + 518597 = 519028

Showing the first eight; more decompositions exist.
