Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518782, here are decompositions:

3 + 518779 = 518782
23 + 518759 = 518782
41 + 518741 = 518782
53 + 518729 = 518782
83 + 518699 = 518782
239 + 518543 = 518782
311 + 518471 = 518782
353 + 518429 = 518782

Showing the first eight; more decompositions exist.
