Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556622, here are decompositions:

199 + 31556423 = 31556622
233 + 31556389 = 31556622
241 + 31556381 = 31556622
269 + 31556353 = 31556622
281 + 31556341 = 31556622
313 + 31556309 = 31556622
373 + 31556249 = 31556622
379 + 31556243 = 31556622

Showing the first eight; more decompositions exist.
