Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556096, here are decompositions:

97 + 31555999 = 31556096
127 + 31555969 = 31556096
139 + 31555957 = 31556096
157 + 31555939 = 31556096
163 + 31555933 = 31556096
223 + 31555873 = 31556096
283 + 31555813 = 31556096
379 + 31555717 = 31556096

Showing the first eight; more decompositions exist.
