Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623528, here are decompositions:

5 + 31623523 = 31623528
7 + 31623521 = 31623528
17 + 31623511 = 31623528
19 + 31623509 = 31623528
29 + 31623499 = 31623528
31 + 31623497 = 31623528
37 + 31623491 = 31623528
47 + 31623481 = 31623528

Showing the first eight; more decompositions exist.
