Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556766, here are decompositions:

19 + 31556747 = 31556766
29 + 31556737 = 31556766
79 + 31556687 = 31556766
113 + 31556653 = 31556766
127 + 31556639 = 31556766
229 + 31556537 = 31556766
277 + 31556489 = 31556766
349 + 31556417 = 31556766

Showing the first eight; more decompositions exist.
