Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556296, here are decompositions:

3 + 31556293 = 31556296
17 + 31556279 = 31556296
47 + 31556249 = 31556296
53 + 31556243 = 31556296
197 + 31556099 = 31556296
263 + 31556033 = 31556296
347 + 31555949 = 31556296
389 + 31555907 = 31556296

Showing the first eight; more decompositions exist.
