Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623546, here are decompositions:

23 + 31623523 = 31623546
37 + 31623509 = 31623546
47 + 31623499 = 31623546
67 + 31623479 = 31623546
103 + 31623443 = 31623546
107 + 31623439 = 31623546
173 + 31623373 = 31623546
337 + 31623209 = 31623546

Showing the first eight; more decompositions exist.
