Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518908, here are decompositions:

41 + 518867 = 518908
101 + 518807 = 518908
107 + 518801 = 518908
149 + 518759 = 518908
167 + 518741 = 518908
179 + 518729 = 518908
191 + 518717 = 518908
251 + 518657 = 518908

Showing the first eight; more decompositions exist.
