Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561822, here are decompositions:

13 + 561809 = 561822
61 + 561761 = 561822
89 + 561733 = 561822
109 + 561713 = 561822
223 + 561599 = 561822
263 + 561559 = 561822
269 + 561553 = 561822
271 + 561551 = 561822

Showing the first eight; more decompositions exist.
