Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518776, here are decompositions:

17 + 518759 = 518776
29 + 518747 = 518776
47 + 518729 = 518776
59 + 518717 = 518776
179 + 518597 = 518776
197 + 518579 = 518776
233 + 518543 = 518776
347 + 518429 = 518776

Showing the first eight; more decompositions exist.
