Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556082, here are decompositions:

71 + 31556011 = 31556082
83 + 31555999 = 31556082
101 + 31555981 = 31556082
113 + 31555969 = 31556082
149 + 31555933 = 31556082
191 + 31555891 = 31556082
211 + 31555871 = 31556082
241 + 31555841 = 31556082

Showing the first eight; more decompositions exist.
