Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491724, here are decompositions:

5 + 491719 = 491724
17 + 491707 = 491724
47 + 491677 = 491724
71 + 491653 = 491724
73 + 491651 = 491724
97 + 491627 = 491724
113 + 491611 = 491724
131 + 491593 = 491724

Showing the first eight; more decompositions exist.
