Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556482, here are decompositions:

3 + 31556479 = 31556482
5 + 31556477 = 31556482
59 + 31556423 = 31556482
101 + 31556381 = 31556482
173 + 31556309 = 31556482
179 + 31556303 = 31556482
233 + 31556249 = 31556482
239 + 31556243 = 31556482

Showing the first eight; more decompositions exist.
