Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556704, here are decompositions:

17 + 31556687 = 31556704
167 + 31556537 = 31556704
227 + 31556477 = 31556704
281 + 31556423 = 31556704
401 + 31556303 = 31556704
461 + 31556243 = 31556704
503 + 31556201 = 31556704
563 + 31556141 = 31556704

Showing the first eight; more decompositions exist.
