Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556132, here are decompositions:

19 + 31556113 = 31556132
151 + 31555981 = 31556132
163 + 31555969 = 31556132
193 + 31555939 = 31556132
199 + 31555933 = 31556132
211 + 31555921 = 31556132
241 + 31555891 = 31556132
499 + 31555633 = 31556132

Showing the first eight; more decompositions exist.
