Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519012, here are decompositions:

23 + 518989 = 519012
29 + 518983 = 519012
31 + 518981 = 519012
59 + 518953 = 519012
79 + 518933 = 519012
101 + 518911 = 519012
149 + 518863 = 519012
181 + 518831 = 519012

Showing the first eight; more decompositions exist.
