Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518316, here are decompositions:

5 + 518311 = 518316
17 + 518299 = 518316
67 + 518249 = 518316
79 + 518237 = 518316
83 + 518233 = 518316
107 + 518209 = 518316
109 + 518207 = 518316
137 + 518179 = 518316

Showing the first eight; more decompositions exist.
