Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518970, here are decompositions:

17 + 518953 = 518970
37 + 518933 = 518970
59 + 518911 = 518970
103 + 518867 = 518970
107 + 518863 = 518970
139 + 518831 = 518970
157 + 518813 = 518970
163 + 518807 = 518970

Showing the first eight; more decompositions exist.
