Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597768, here are decompositions:

5 + 31597763 = 31597768
29 + 31597739 = 31597768
47 + 31597721 = 31597768
71 + 31597697 = 31597768
197 + 31597571 = 31597768
227 + 31597541 = 31597768
401 + 31597367 = 31597768
431 + 31597337 = 31597768

Showing the first eight; more decompositions exist.
