Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518992, here are decompositions:

3 + 518989 = 518992
11 + 518981 = 518992
59 + 518933 = 518992
179 + 518813 = 518992
191 + 518801 = 518992
233 + 518759 = 518992
251 + 518741 = 518992
263 + 518729 = 518992

Showing the first eight; more decompositions exist.
