Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518322, here are decompositions:

11 + 518311 = 518322
23 + 518299 = 518322
31 + 518291 = 518322
61 + 518261 = 518322
73 + 518249 = 518322
83 + 518239 = 518322
89 + 518233 = 518322
113 + 518209 = 518322

Showing the first eight; more decompositions exist.
