Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556968, here are decompositions:

11 + 31556957 = 31556968
29 + 31556939 = 31556968
59 + 31556909 = 31556968
197 + 31556771 = 31556968
227 + 31556741 = 31556968
281 + 31556687 = 31556968
431 + 31556537 = 31556968
467 + 31556501 = 31556968

Showing the first eight; more decompositions exist.
