Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556098, here are decompositions:

17 + 31556081 = 31556098
107 + 31555991 = 31556098
131 + 31555967 = 31556098
149 + 31555949 = 31556098
191 + 31555907 = 31556098
227 + 31555871 = 31556098
257 + 31555841 = 31556098
317 + 31555781 = 31556098

Showing the first eight; more decompositions exist.
