Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31996, here are decompositions:

5 + 31991 = 31996
23 + 31973 = 31996
89 + 31907 = 31996
113 + 31883 = 31996
137 + 31859 = 31996
149 + 31847 = 31996
179 + 31817 = 31996
197 + 31799 = 31996

Showing the first eight; more decompositions exist.
