Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518698, here are decompositions:

41 + 518657 = 518698
101 + 518597 = 518698
227 + 518471 = 518698
251 + 518447 = 518698
269 + 518429 = 518698
281 + 518417 = 518698
311 + 518387 = 518698
449 + 518249 = 518698

Showing the first eight; more decompositions exist.
