Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556822, here are decompositions:

19 + 31556803 = 31556822
43 + 31556779 = 31556822
433 + 31556389 = 31556822
499 + 31556323 = 31556822
673 + 31556149 = 31556822
709 + 31556113 = 31556822
811 + 31556011 = 31556822
823 + 31555999 = 31556822

Showing the first eight; more decompositions exist.
