Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556014, here are decompositions:

3 + 31556011 = 31556014
23 + 31555991 = 31556014
47 + 31555967 = 31556014
107 + 31555907 = 31556014
137 + 31555877 = 31556014
173 + 31555841 = 31556014
233 + 31555781 = 31556014
251 + 31555763 = 31556014

Showing the first eight; more decompositions exist.
