Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518346, here are decompositions:

5 + 518341 = 518346
19 + 518327 = 518346
47 + 518299 = 518346
97 + 518249 = 518346
107 + 518239 = 518346
109 + 518237 = 518346
113 + 518233 = 518346
137 + 518209 = 518346

Showing the first eight; more decompositions exist.
