Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518150, here are decompositions:

13 + 518137 = 518150
19 + 518131 = 518150
37 + 518113 = 518150
67 + 518083 = 518150
103 + 518047 = 518150
151 + 517999 = 518150
223 + 517927 = 518150
277 + 517873 = 518150

Showing the first eight; more decompositions exist.
