Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623506, here are decompositions:

7 + 31623499 = 31623506
67 + 31623439 = 31623506
163 + 31623343 = 31623506
283 + 31623223 = 31623506
307 + 31623199 = 31623506
337 + 31623169 = 31623506
547 + 31622959 = 31623506
613 + 31622893 = 31623506

Showing the first eight; more decompositions exist.
