Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551228, here are decompositions:

31 + 551197 = 551228
211 + 551017 = 551228
277 + 550951 = 551228
367 + 550861 = 551228
397 + 550831 = 551228
439 + 550789 = 551228
571 + 550657 = 551228
577 + 550651 = 551228

Showing the first eight; more decompositions exist.
