Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556084, here are decompositions:

3 + 31556081 = 31556084
73 + 31556011 = 31556084
103 + 31555981 = 31556084
127 + 31555957 = 31556084
151 + 31555933 = 31556084
163 + 31555921 = 31556084
193 + 31555891 = 31556084
211 + 31555873 = 31556084

Showing the first eight; more decompositions exist.
