Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536440, here are decompositions:

17 + 536423 = 536440
41 + 536399 = 536440
83 + 536357 = 536440
167 + 536273 = 536440
173 + 536267 = 536440
197 + 536243 = 536440
227 + 536213 = 536440
251 + 536189 = 536440

Showing the first eight; more decompositions exist.
