Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518310, here are decompositions:

11 + 518299 = 518310
19 + 518291 = 518310
61 + 518249 = 518310
71 + 518239 = 518310
73 + 518237 = 518310
101 + 518209 = 518310
103 + 518207 = 518310
131 + 518179 = 518310

Showing the first eight; more decompositions exist.
