Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596928, here are decompositions:

5 + 31596923 = 31596928
29 + 31596899 = 31596928
47 + 31596881 = 31596928
71 + 31596857 = 31596928
89 + 31596839 = 31596928
107 + 31596821 = 31596928
131 + 31596797 = 31596928
179 + 31596749 = 31596928

Showing the first eight; more decompositions exist.
