Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556192, here are decompositions:

43 + 31556149 = 31556192
79 + 31556113 = 31556192
181 + 31556011 = 31556192
193 + 31555999 = 31556192
211 + 31555981 = 31556192
223 + 31555969 = 31556192
271 + 31555921 = 31556192
379 + 31555813 = 31556192

Showing the first eight; more decompositions exist.
