Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518216, here are decompositions:

7 + 518209 = 518216
37 + 518179 = 518216
79 + 518137 = 518216
103 + 518113 = 518216
157 + 518059 = 518216
199 + 518017 = 518216
487 + 517729 = 518216
499 + 517717 = 518216

Showing the first eight; more decompositions exist.
