Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516962, here are decompositions:

11 + 31516951 = 31516962
73 + 31516889 = 31516962
83 + 31516879 = 31516962
151 + 31516811 = 31516962
173 + 31516789 = 31516962
181 + 31516781 = 31516962
233 + 31516729 = 31516962
263 + 31516699 = 31516962

Showing the first eight; more decompositions exist.
