Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556466, here are decompositions:

5 + 31556461 = 31556466
43 + 31556423 = 31556466
59 + 31556407 = 31556466
113 + 31556353 = 31556466
157 + 31556309 = 31556466
163 + 31556303 = 31556466
173 + 31556293 = 31556466
223 + 31556243 = 31556466

Showing the first eight; more decompositions exist.
