Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551356, here are decompositions:

17 + 551339 = 551356
59 + 551297 = 551356
137 + 551219 = 551356
149 + 551207 = 551356
227 + 551129 = 551356
257 + 551099 = 551356
263 + 551093 = 551356
293 + 551063 = 551356

Showing the first eight; more decompositions exist.
