Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518274, here are decompositions:

13 + 518261 = 518274
37 + 518237 = 518274
41 + 518233 = 518274
67 + 518207 = 518274
83 + 518191 = 518274
103 + 518171 = 518274
137 + 518137 = 518274
151 + 518123 = 518274

Showing the first eight; more decompositions exist.
