Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556150, here are decompositions:

7 + 31556143 = 31556150
37 + 31556113 = 31556150
139 + 31556011 = 31556150
151 + 31555999 = 31556150
181 + 31555969 = 31556150
193 + 31555957 = 31556150
211 + 31555939 = 31556150
229 + 31555921 = 31556150

Showing the first eight; more decompositions exist.
