Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623514, here are decompositions:

3 + 31623511 = 31623514
5 + 31623509 = 31623514
17 + 31623497 = 31623514
23 + 31623491 = 31623514
53 + 31623461 = 31623514
71 + 31623443 = 31623514
137 + 31623377 = 31623514
257 + 31623257 = 31623514

Showing the first eight; more decompositions exist.
