Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556108, here are decompositions:

97 + 31556011 = 31556108
109 + 31555999 = 31556108
127 + 31555981 = 31556108
139 + 31555969 = 31556108
151 + 31555957 = 31556108
457 + 31555651 = 31556108
811 + 31555297 = 31556108
937 + 31555171 = 31556108

Showing the first eight; more decompositions exist.
