Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556814, here are decompositions:

11 + 31556803 = 31556814
43 + 31556771 = 31556814
67 + 31556747 = 31556814
73 + 31556741 = 31556814
127 + 31556687 = 31556814
167 + 31556647 = 31556814
257 + 31556557 = 31556814
277 + 31556537 = 31556814

Showing the first eight; more decompositions exist.
