Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491748, here are decompositions:

11 + 491737 = 491748
17 + 491731 = 491748
29 + 491719 = 491748
41 + 491707 = 491748
71 + 491677 = 491748
79 + 491669 = 491748
97 + 491651 = 491748
109 + 491639 = 491748

Showing the first eight; more decompositions exist.
