Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568956, here are decompositions:

17 + 31568939 = 31568956
47 + 31568909 = 31568956
59 + 31568897 = 31568956
113 + 31568843 = 31568956
233 + 31568723 = 31568956
557 + 31568399 = 31568956
563 + 31568393 = 31568956
569 + 31568387 = 31568956

Showing the first eight; more decompositions exist.
