Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551320, here are decompositions:

23 + 551297 = 551320
89 + 551231 = 551320
101 + 551219 = 551320
113 + 551207 = 551320
191 + 551129 = 551320
227 + 551093 = 551320
251 + 551069 = 551320
257 + 551063 = 551320

Showing the first eight; more decompositions exist.
