Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477962, here are decompositions:

11 + 31477951 = 31477962
79 + 31477883 = 31477962
83 + 31477879 = 31477962
151 + 31477811 = 31477962
163 + 31477799 = 31477962
181 + 31477781 = 31477962
211 + 31477751 = 31477962
233 + 31477729 = 31477962

Showing the first eight; more decompositions exist.
