Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501962, here are decompositions:

5 + 31501957 = 31501962
83 + 31501879 = 31501962
101 + 31501861 = 31501962
113 + 31501849 = 31501962
131 + 31501831 = 31501962
139 + 31501823 = 31501962
181 + 31501781 = 31501962
211 + 31501751 = 31501962

Showing the first eight; more decompositions exist.
