Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556634, here are decompositions:

97 + 31556537 = 31556634
157 + 31556477 = 31556634
167 + 31556467 = 31556634
173 + 31556461 = 31556634
211 + 31556423 = 31556634
227 + 31556407 = 31556634
281 + 31556353 = 31556634
293 + 31556341 = 31556634

Showing the first eight; more decompositions exist.
