Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491794, here are decompositions:

5 + 491789 = 491794
11 + 491783 = 491794
47 + 491747 = 491794
167 + 491627 = 491794
257 + 491537 = 491794
263 + 491531 = 491794
293 + 491501 = 491794
311 + 491483 = 491794

Showing the first eight; more decompositions exist.
