Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556102, here are decompositions:

3 + 31556099 = 31556102
103 + 31555999 = 31556102
163 + 31555939 = 31556102
181 + 31555921 = 31556102
211 + 31555891 = 31556102
229 + 31555873 = 31556102
439 + 31555663 = 31556102
499 + 31555603 = 31556102

Showing the first eight; more decompositions exist.
