Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518854, here are decompositions:

23 + 518831 = 518854
41 + 518813 = 518854
47 + 518807 = 518854
53 + 518801 = 518854
107 + 518747 = 518854
113 + 518741 = 518854
137 + 518717 = 518854
197 + 518657 = 518854

Showing the first eight; more decompositions exist.
