Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518494, here are decompositions:

23 + 518471 = 518494
47 + 518447 = 518494
83 + 518411 = 518494
107 + 518387 = 518494
167 + 518327 = 518494
233 + 518261 = 518494
257 + 518237 = 518494
503 + 517991 = 518494

Showing the first eight; more decompositions exist.
