Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563962, here are decompositions:

13 + 31563949 = 31563962
19 + 31563943 = 31563962
229 + 31563733 = 31563962
499 + 31563463 = 31563962
571 + 31563391 = 31563962
613 + 31563349 = 31563962
709 + 31563253 = 31563962
769 + 31563193 = 31563962

Showing the first eight; more decompositions exist.
