Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551338, here are decompositions:

17 + 551321 = 551338
41 + 551297 = 551338
107 + 551231 = 551338
131 + 551207 = 551338
239 + 551099 = 551338
269 + 551069 = 551338
311 + 551027 = 551338
401 + 550937 = 551338

Showing the first eight; more decompositions exist.
