Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518338, here are decompositions:

11 + 518327 = 518338
47 + 518291 = 518338
89 + 518249 = 518338
101 + 518237 = 518338
131 + 518207 = 518338
167 + 518171 = 518338
179 + 518159 = 518338
239 + 518099 = 518338

Showing the first eight; more decompositions exist.
