Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532882, here are decompositions:

19 + 31532863 = 31532882
223 + 31532659 = 31532882
229 + 31532653 = 31532882
331 + 31532551 = 31532882
541 + 31532341 = 31532882
613 + 31532269 = 31532882
673 + 31532209 = 31532882
769 + 31532113 = 31532882

Showing the first eight; more decompositions exist.
