Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556794, here are decompositions:

23 + 31556771 = 31556794
47 + 31556747 = 31556794
53 + 31556741 = 31556794
107 + 31556687 = 31556794
257 + 31556537 = 31556794
293 + 31556501 = 31556794
317 + 31556477 = 31556794
491 + 31556303 = 31556794

Showing the first eight; more decompositions exist.
