Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556094, here are decompositions:

13 + 31556081 = 31556094
61 + 31556033 = 31556094
83 + 31556011 = 31556094
103 + 31555991 = 31556094
113 + 31555981 = 31556094
127 + 31555967 = 31556094
137 + 31555957 = 31556094
173 + 31555921 = 31556094

Showing the first eight; more decompositions exist.
