Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561560, here are decompositions:

7 + 561553 = 561560
31 + 561529 = 561560
151 + 561409 = 561560
193 + 561367 = 561560
283 + 561277 = 561560
331 + 561229 = 561560
379 + 561181 = 561560
457 + 561103 = 561560

Showing the first eight; more decompositions exist.
