Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518764, here are decompositions:

3 + 518761 = 518764
5 + 518759 = 518764
17 + 518747 = 518764
23 + 518741 = 518764
47 + 518717 = 518764
107 + 518657 = 518764
167 + 518597 = 518764
293 + 518471 = 518764

Showing the first eight; more decompositions exist.
