Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623736, here are decompositions:

5 + 31623731 = 31623736
29 + 31623707 = 31623736
113 + 31623623 = 31623736
227 + 31623509 = 31623736
239 + 31623497 = 31623736
257 + 31623479 = 31623736
293 + 31623443 = 31623736
359 + 31623377 = 31623736

Showing the first eight; more decompositions exist.
