Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491854, here are decompositions:

3 + 491851 = 491854
17 + 491837 = 491854
71 + 491783 = 491854
107 + 491747 = 491854
227 + 491627 = 491854
263 + 491591 = 491854
317 + 491537 = 491854
353 + 491501 = 491854

Showing the first eight; more decompositions exist.
