Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597068, here are decompositions:

17 + 31597051 = 31597068
37 + 31597031 = 31597068
71 + 31596997 = 31597068
179 + 31596889 = 31597068
211 + 31596857 = 31597068
229 + 31596839 = 31597068
271 + 31596797 = 31597068
311 + 31596757 = 31597068

Showing the first eight; more decompositions exist.
