Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556124, here are decompositions:

11 + 31556113 = 31556124
43 + 31556081 = 31556124
113 + 31556011 = 31556124
157 + 31555967 = 31556124
167 + 31555957 = 31556124
191 + 31555933 = 31556124
233 + 31555891 = 31556124
251 + 31555873 = 31556124

Showing the first eight; more decompositions exist.
