Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518510, here are decompositions:

37 + 518473 = 518510
43 + 518467 = 518510
79 + 518431 = 518510
199 + 518311 = 518510
211 + 518299 = 518510
271 + 518239 = 518510
277 + 518233 = 518510
331 + 518179 = 518510

Showing the first eight; more decompositions exist.
