Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518124, here are decompositions:

11 + 518113 = 518124
23 + 518101 = 518124
41 + 518083 = 518124
67 + 518057 = 518124
107 + 518017 = 518124
157 + 517967 = 518124
193 + 517931 = 518124
197 + 517927 = 518124

Showing the first eight; more decompositions exist.
