Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551236, here are decompositions:

3 + 551233 = 551236
5 + 551231 = 551236
17 + 551219 = 551236
29 + 551207 = 551236
107 + 551129 = 551236
137 + 551099 = 551236
167 + 551069 = 551236
173 + 551063 = 551236

Showing the first eight; more decompositions exist.
