Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518464, here are decompositions:

17 + 518447 = 518464
47 + 518417 = 518464
53 + 518411 = 518464
137 + 518327 = 518464
173 + 518291 = 518464
227 + 518237 = 518464
257 + 518207 = 518464
293 + 518171 = 518464

Showing the first eight; more decompositions exist.
