Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31962, here are decompositions:

5 + 31957 = 31962
71 + 31891 = 31962
79 + 31883 = 31962
89 + 31873 = 31962
103 + 31859 = 31962
113 + 31849 = 31962
163 + 31799 = 31962
191 + 31771 = 31962

Showing the first eight; more decompositions exist.
