Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561584, here are decompositions:

31 + 561553 = 561584
211 + 561373 = 561584
241 + 561343 = 561584
271 + 561313 = 561584
277 + 561307 = 561584
307 + 561277 = 561584
487 + 561097 = 561584
523 + 561061 = 561584

Showing the first eight; more decompositions exist.
