Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491682, here are decompositions:

5 + 491677 = 491682
13 + 491669 = 491682
29 + 491653 = 491682
31 + 491651 = 491682
43 + 491639 = 491682
71 + 491611 = 491682
89 + 491593 = 491682
101 + 491581 = 491682

Showing the first eight; more decompositions exist.
