Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491850, here are decompositions:

13 + 491837 = 491850
17 + 491833 = 491850
31 + 491819 = 491850
53 + 491797 = 491850
61 + 491789 = 491850
67 + 491783 = 491850
103 + 491747 = 491850
113 + 491737 = 491850

Showing the first eight; more decompositions exist.
