Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551326, here are decompositions:

5 + 551321 = 551326
29 + 551297 = 551326
107 + 551219 = 551326
197 + 551129 = 551326
227 + 551099 = 551326
233 + 551093 = 551326
257 + 551069 = 551326
263 + 551063 = 551326

Showing the first eight; more decompositions exist.
