Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556162, here are decompositions:

13 + 31556149 = 31556162
19 + 31556143 = 31556162
151 + 31556011 = 31556162
163 + 31555999 = 31556162
181 + 31555981 = 31556162
193 + 31555969 = 31556162
223 + 31555939 = 31556162
229 + 31555933 = 31556162

Showing the first eight; more decompositions exist.
