Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597024, here are decompositions:

47 + 31596977 = 31597024
101 + 31596923 = 31597024
167 + 31596857 = 31597024
227 + 31596797 = 31597024
281 + 31596743 = 31597024
311 + 31596713 = 31597024
317 + 31596707 = 31597024
353 + 31596671 = 31597024

Showing the first eight; more decompositions exist.
