Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518798, here are decompositions:

19 + 518779 = 518798
31 + 518767 = 518798
37 + 518761 = 518798
61 + 518737 = 518798
109 + 518689 = 518798
211 + 518587 = 518798
277 + 518521 = 518798
331 + 518467 = 518798

Showing the first eight; more decompositions exist.
