Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556024, here are decompositions:

13 + 31556011 = 31556024
43 + 31555981 = 31556024
67 + 31555957 = 31556024
103 + 31555921 = 31556024
151 + 31555873 = 31556024
211 + 31555813 = 31556024
307 + 31555717 = 31556024
373 + 31555651 = 31556024

Showing the first eight; more decompositions exist.
