Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556914, here are decompositions:

3 + 31556911 = 31556914
5 + 31556909 = 31556914
101 + 31556813 = 31556914
167 + 31556747 = 31556914
173 + 31556741 = 31556914
227 + 31556687 = 31556914
491 + 31556423 = 31556914
773 + 31556141 = 31556914

Showing the first eight; more decompositions exist.
