Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518886, here are decompositions:

19 + 518867 = 518886
23 + 518863 = 518886
73 + 518813 = 518886
79 + 518807 = 518886
83 + 518803 = 518886
107 + 518779 = 518886
127 + 518759 = 518886
139 + 518747 = 518886

Showing the first eight; more decompositions exist.
