Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556966, here are decompositions:

43 + 31556923 = 31556966
97 + 31556869 = 31556966
109 + 31556857 = 31556966
139 + 31556827 = 31556966
163 + 31556803 = 31556966
229 + 31556737 = 31556966
313 + 31556653 = 31556966
409 + 31556557 = 31556966

Showing the first eight; more decompositions exist.
