Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561422, here are decompositions:

3 + 561419 = 561422
13 + 561409 = 561422
79 + 561343 = 561422
109 + 561313 = 561422
193 + 561229 = 561422
223 + 561199 = 561422
241 + 561181 = 561422
313 + 561109 = 561422

Showing the first eight; more decompositions exist.
