Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551266, here are decompositions:

47 + 551219 = 551266
59 + 551207 = 551266
137 + 551129 = 551266
167 + 551099 = 551266
173 + 551093 = 551266
197 + 551069 = 551266
227 + 551039 = 551266
239 + 551027 = 551266

Showing the first eight; more decompositions exist.
