Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556176, here are decompositions:

227 + 31555949 = 31556176
269 + 31555907 = 31556176
479 + 31555697 = 31556176
569 + 31555607 = 31556176
683 + 31555493 = 31556176
857 + 31555319 = 31556176
863 + 31555313 = 31556176
887 + 31555289 = 31556176

Showing the first eight; more decompositions exist.
