Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623682, here are decompositions:

11 + 31623671 = 31623682
59 + 31623623 = 31623682
173 + 31623509 = 31623682
191 + 31623491 = 31623682
239 + 31623443 = 31623682
509 + 31623173 = 31623682
569 + 31623113 = 31623682
641 + 31623041 = 31623682

Showing the first eight; more decompositions exist.
