Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561798, here are decompositions:

11 + 561787 = 561798
31 + 561767 = 561798
37 + 561761 = 561798
131 + 561667 = 561798
191 + 561607 = 561798
199 + 561599 = 561798
239 + 561559 = 561798
269 + 561529 = 561798

Showing the first eight; more decompositions exist.
