Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568826, here are decompositions:

17 + 31568809 = 31568826
59 + 31568767 = 31568826
83 + 31568743 = 31568826
89 + 31568737 = 31568826
103 + 31568723 = 31568826
197 + 31568629 = 31568826
239 + 31568587 = 31568826
283 + 31568543 = 31568826

Showing the first eight; more decompositions exist.
