Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551272, here are decompositions:

3 + 551269 = 551272
41 + 551231 = 551272
53 + 551219 = 551272
173 + 551099 = 551272
179 + 551093 = 551272
233 + 551039 = 551272
269 + 551003 = 551272
311 + 550961 = 551272

Showing the first eight; more decompositions exist.
