Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586966, here are decompositions:

97 + 31586869 = 31586966
127 + 31586839 = 31586966
157 + 31586809 = 31586966
163 + 31586803 = 31586966
223 + 31586743 = 31586966
277 + 31586689 = 31586966
349 + 31586617 = 31586966
457 + 31586509 = 31586966

Showing the first eight; more decompositions exist.
