Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491836, here are decompositions:

3 + 491833 = 491836
17 + 491819 = 491836
47 + 491789 = 491836
53 + 491783 = 491836
89 + 491747 = 491836
167 + 491669 = 491836
197 + 491639 = 491836
347 + 491489 = 491836

Showing the first eight; more decompositions exist.
