Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556298, here are decompositions:

5 + 31556293 = 31556298
19 + 31556279 = 31556298
97 + 31556201 = 31556298
149 + 31556149 = 31556298
157 + 31556141 = 31556298
199 + 31556099 = 31556298
307 + 31555991 = 31556298
317 + 31555981 = 31556298

Showing the first eight; more decompositions exist.
