Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518422, here are decompositions:

5 + 518417 = 518422
11 + 518411 = 518422
131 + 518291 = 518422
173 + 518249 = 518422
251 + 518171 = 518422
263 + 518159 = 518422
269 + 518153 = 518422
293 + 518129 = 518422

Showing the first eight; more decompositions exist.
