Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31960, here are decompositions:

3 + 31957 = 31960
53 + 31907 = 31960
101 + 31859 = 31960
113 + 31847 = 31960
167 + 31793 = 31960
191 + 31769 = 31960
233 + 31727 = 31960
239 + 31721 = 31960

Showing the first eight; more decompositions exist.
