Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556056, here are decompositions:

23 + 31556033 = 31556056
89 + 31555967 = 31556056
107 + 31555949 = 31556056
149 + 31555907 = 31556056
179 + 31555877 = 31556056
293 + 31555763 = 31556056
317 + 31555739 = 31556056
359 + 31555697 = 31556056

Showing the first eight; more decompositions exist.
