Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556266, here are decompositions:

17 + 31556249 = 31556266
23 + 31556243 = 31556266
167 + 31556099 = 31556266
233 + 31556033 = 31556266
317 + 31555949 = 31556266
359 + 31555907 = 31556266
389 + 31555877 = 31556266
503 + 31555763 = 31556266

Showing the first eight; more decompositions exist.
