Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556936, here are decompositions:

13 + 31556923 = 31556936
67 + 31556869 = 31556936
79 + 31556857 = 31556936
109 + 31556827 = 31556936
157 + 31556779 = 31556936
199 + 31556737 = 31556936
283 + 31556653 = 31556936
379 + 31556557 = 31556936

Showing the first eight; more decompositions exist.
