Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623724, here are decompositions:

3 + 31623721 = 31623724
17 + 31623707 = 31623724
23 + 31623701 = 31623724
53 + 31623671 = 31623724
101 + 31623623 = 31623724
107 + 31623617 = 31623724
227 + 31623497 = 31623724
233 + 31623491 = 31623724

Showing the first eight; more decompositions exist.
