Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623694, here are decompositions:

23 + 31623671 = 31623694
71 + 31623623 = 31623694
173 + 31623521 = 31623694
197 + 31623497 = 31623694
233 + 31623461 = 31623694
251 + 31623443 = 31623694
317 + 31623377 = 31623694
521 + 31623173 = 31623694

Showing the first eight; more decompositions exist.
