Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518994, here are decompositions:

5 + 518989 = 518994
11 + 518983 = 518994
13 + 518981 = 518994
41 + 518953 = 518994
61 + 518933 = 518994
83 + 518911 = 518994
101 + 518893 = 518994
127 + 518867 = 518994

Showing the first eight; more decompositions exist.
