Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561622, here are decompositions:

23 + 561599 = 561622
71 + 561551 = 561622
101 + 561521 = 561622
233 + 561389 = 561622
263 + 561359 = 561622
431 + 561191 = 561622
449 + 561173 = 561622
461 + 561161 = 561622

Showing the first eight; more decompositions exist.
