Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623706, here are decompositions:

3 + 31623703 = 31623706
5 + 31623701 = 31623706
83 + 31623623 = 31623706
89 + 31623617 = 31623706
197 + 31623509 = 31623706
227 + 31623479 = 31623706
263 + 31623443 = 31623706
449 + 31623257 = 31623706

Showing the first eight; more decompositions exist.
