Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556310, here are decompositions:

7 + 31556303 = 31556310
17 + 31556293 = 31556310
31 + 31556279 = 31556310
61 + 31556249 = 31556310
67 + 31556243 = 31556310
109 + 31556201 = 31556310
167 + 31556143 = 31556310
197 + 31556113 = 31556310

Showing the first eight; more decompositions exist.
