Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623606, here are decompositions:

17 + 31623589 = 31623606
83 + 31623523 = 31623606
97 + 31623509 = 31623606
107 + 31623499 = 31623606
109 + 31623497 = 31623606
127 + 31623479 = 31623606
163 + 31623443 = 31623606
167 + 31623439 = 31623606

Showing the first eight; more decompositions exist.
