Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491766, here are decompositions:

19 + 491747 = 491766
29 + 491737 = 491766
47 + 491719 = 491766
59 + 491707 = 491766
89 + 491677 = 491766
97 + 491669 = 491766
113 + 491653 = 491766
127 + 491639 = 491766

Showing the first eight; more decompositions exist.
