Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556926, here are decompositions:

3 + 31556923 = 31556926
17 + 31556909 = 31556926
113 + 31556813 = 31556926
179 + 31556747 = 31556926
239 + 31556687 = 31556926
389 + 31556537 = 31556926
449 + 31556477 = 31556926
503 + 31556423 = 31556926

Showing the first eight; more decompositions exist.
