Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623934, here are decompositions:

3 + 31623931 = 31623934
5 + 31623929 = 31623934
47 + 31623887 = 31623934
113 + 31623821 = 31623934
137 + 31623797 = 31623934
227 + 31623707 = 31623934
233 + 31623701 = 31623934
263 + 31623671 = 31623934

Showing the first eight; more decompositions exist.
