Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623612, here are decompositions:

5 + 31623607 = 31623612
23 + 31623589 = 31623612
89 + 31623523 = 31623612
101 + 31623511 = 31623612
103 + 31623509 = 31623612
113 + 31623499 = 31623612
131 + 31623481 = 31623612
151 + 31623461 = 31623612

Showing the first eight; more decompositions exist.
