Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556326, here are decompositions:

3 + 31556323 = 31556326
17 + 31556309 = 31556326
23 + 31556303 = 31556326
47 + 31556279 = 31556326
83 + 31556243 = 31556326
227 + 31556099 = 31556326
293 + 31556033 = 31556326
359 + 31555967 = 31556326

Showing the first eight; more decompositions exist.
