Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556956, here are decompositions:

17 + 31556939 = 31556956
47 + 31556909 = 31556956
269 + 31556687 = 31556956
317 + 31556639 = 31556956
419 + 31556537 = 31556956
467 + 31556489 = 31556956
479 + 31556477 = 31556956
647 + 31556309 = 31556956

Showing the first eight; more decompositions exist.
