Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518308, here are decompositions:

17 + 518291 = 518308
47 + 518261 = 518308
59 + 518249 = 518308
71 + 518237 = 518308
101 + 518207 = 518308
137 + 518171 = 518308
149 + 518159 = 518308
179 + 518129 = 518308

Showing the first eight; more decompositions exist.
