Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623502, here are decompositions:

3 + 31623499 = 31623502
5 + 31623497 = 31623502
11 + 31623491 = 31623502
23 + 31623479 = 31623502
41 + 31623461 = 31623502
59 + 31623443 = 31623502
293 + 31623209 = 31623502
389 + 31623113 = 31623502

Showing the first eight; more decompositions exist.
