Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551722, here are decompositions:

5 + 551717 = 551722
29 + 551693 = 551722
71 + 551651 = 551722
173 + 551549 = 551722
179 + 551543 = 551722
233 + 551489 = 551722
239 + 551483 = 551722
359 + 551363 = 551722

Showing the first eight; more decompositions exist.
