Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518168, here are decompositions:

31 + 518137 = 518168
37 + 518131 = 518168
67 + 518101 = 518168
109 + 518059 = 518168
151 + 518017 = 518168
241 + 517927 = 518168
307 + 517861 = 518168
337 + 517831 = 518168

Showing the first eight; more decompositions exist.
