Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596988, here are decompositions:

11 + 31596977 = 31596988
89 + 31596899 = 31596988
107 + 31596881 = 31596988
131 + 31596857 = 31596988
149 + 31596839 = 31596988
167 + 31596821 = 31596988
191 + 31596797 = 31596988
239 + 31596749 = 31596988

Showing the first eight; more decompositions exist.
