Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559716, here are decompositions:

17 + 31559699 = 31559716
29 + 31559687 = 31559716
179 + 31559537 = 31559716
269 + 31559447 = 31559716
509 + 31559207 = 31559716
647 + 31559069 = 31559716
719 + 31558997 = 31559716
743 + 31558973 = 31559716

Showing the first eight; more decompositions exist.
