Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518828, here are decompositions:

19 + 518809 = 518828
61 + 518767 = 518828
67 + 518761 = 518828
139 + 518689 = 518828
241 + 518587 = 518828
307 + 518521 = 518828
397 + 518431 = 518828
439 + 518389 = 518828

Showing the first eight; more decompositions exist.
