Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518268, here are decompositions:

7 + 518261 = 518268
19 + 518249 = 518268
29 + 518239 = 518268
31 + 518237 = 518268
59 + 518209 = 518268
61 + 518207 = 518268
89 + 518179 = 518268
97 + 518171 = 518268

Showing the first eight; more decompositions exist.
