Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556476, here are decompositions:

53 + 31556423 = 31556476
59 + 31556417 = 31556476
167 + 31556309 = 31556476
173 + 31556303 = 31556476
197 + 31556279 = 31556476
227 + 31556249 = 31556476
233 + 31556243 = 31556476
443 + 31556033 = 31556476

Showing the first eight; more decompositions exist.
