Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518256, here are decompositions:

7 + 518249 = 518256
17 + 518239 = 518256
19 + 518237 = 518256
23 + 518233 = 518256
47 + 518209 = 518256
97 + 518159 = 518256
103 + 518153 = 518256
127 + 518129 = 518256

Showing the first eight; more decompositions exist.
