Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518226, here are decompositions:

17 + 518209 = 518226
19 + 518207 = 518226
47 + 518179 = 518226
67 + 518159 = 518226
73 + 518153 = 518226
89 + 518137 = 518226
97 + 518129 = 518226
103 + 518123 = 518226

Showing the first eight; more decompositions exist.
