Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518250, here are decompositions:

11 + 518239 = 518250
13 + 518237 = 518250
17 + 518233 = 518250
41 + 518209 = 518250
43 + 518207 = 518250
59 + 518191 = 518250
71 + 518179 = 518250
79 + 518171 = 518250

Showing the first eight; more decompositions exist.
