Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551822, here are decompositions:

13 + 551809 = 551822
79 + 551743 = 551822
109 + 551713 = 551822
151 + 551671 = 551822
163 + 551659 = 551822
241 + 551581 = 551822
283 + 551539 = 551822
379 + 551443 = 551822

Showing the first eight; more decompositions exist.
