Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623516, here are decompositions:

5 + 31623511 = 31623516
7 + 31623509 = 31623516
17 + 31623499 = 31623516
19 + 31623497 = 31623516
37 + 31623479 = 31623516
73 + 31623443 = 31623516
139 + 31623377 = 31623516
173 + 31623343 = 31623516

Showing the first eight; more decompositions exist.
