Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31984, here are decompositions:

3 + 31981 = 31984
11 + 31973 = 31984
101 + 31883 = 31984
137 + 31847 = 31984
167 + 31817 = 31984
191 + 31793 = 31984
233 + 31751 = 31984
257 + 31727 = 31984

Showing the first eight; more decompositions exist.
