Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556068, here are decompositions:

101 + 31555967 = 31556068
191 + 31555877 = 31556068
197 + 31555871 = 31556068
227 + 31555841 = 31556068
461 + 31555607 = 31556068
809 + 31555259 = 31556068
839 + 31555229 = 31556068
857 + 31555211 = 31556068

Showing the first eight; more decompositions exist.
