Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519018, here are decompositions:

7 + 519011 = 519018
29 + 518989 = 519018
37 + 518981 = 519018
107 + 518911 = 519018
151 + 518867 = 519018
211 + 518807 = 519018
239 + 518779 = 519018
251 + 518767 = 519018

Showing the first eight; more decompositions exist.
