Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518208, here are decompositions:

17 + 518191 = 518208
29 + 518179 = 518208
37 + 518171 = 518208
71 + 518137 = 518208
79 + 518129 = 518208
107 + 518101 = 518208
109 + 518099 = 518208
149 + 518059 = 518208

Showing the first eight; more decompositions exist.
