Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513666, here are decompositions:

17 + 513649 = 513666
73 + 513593 = 513666
137 + 513529 = 513666
157 + 513509 = 513666
193 + 513473 = 513666
227 + 513439 = 513666
239 + 513427 = 513666
269 + 513397 = 513666

Showing the first eight; more decompositions exist.
