Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563918, here are decompositions:

31 + 563887 = 563918
37 + 563881 = 563918
67 + 563851 = 563918
97 + 563821 = 563918
109 + 563809 = 563918
331 + 563587 = 563918
367 + 563551 = 563918
499 + 563419 = 563918

Showing the first eight; more decompositions exist.
