Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623512, here are decompositions:

3 + 31623509 = 31623512
13 + 31623499 = 31623512
31 + 31623481 = 31623512
73 + 31623439 = 31623512
139 + 31623373 = 31623512
313 + 31623199 = 31623512
331 + 31623181 = 31623512
619 + 31622893 = 31623512

Showing the first eight; more decompositions exist.
