Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556136, here are decompositions:

23 + 31556113 = 31556136
37 + 31556099 = 31556136
103 + 31556033 = 31556136
137 + 31555999 = 31556136
167 + 31555969 = 31556136
179 + 31555957 = 31556136
197 + 31555939 = 31556136
229 + 31555907 = 31556136

Showing the first eight; more decompositions exist.
