Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518946, here are decompositions:

13 + 518933 = 518946
53 + 518893 = 518946
79 + 518867 = 518946
83 + 518863 = 518946
137 + 518809 = 518946
139 + 518807 = 518946
167 + 518779 = 518946
179 + 518767 = 518946

Showing the first eight; more decompositions exist.
