Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31966, here are decompositions:

3 + 31963 = 31966
59 + 31907 = 31966
83 + 31883 = 31966
107 + 31859 = 31966
149 + 31817 = 31966
167 + 31799 = 31966
173 + 31793 = 31966
197 + 31769 = 31966

Showing the first eight; more decompositions exist.
