Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597926, here are decompositions:

13 + 31597913 = 31597926
47 + 31597879 = 31597926
53 + 31597873 = 31597926
83 + 31597843 = 31597926
103 + 31597823 = 31597926
149 + 31597777 = 31597926
163 + 31597763 = 31597926
197 + 31597729 = 31597926

Showing the first eight; more decompositions exist.
