Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2682, here are decompositions:

5 + 2677 = 2682
11 + 2671 = 2682
19 + 2663 = 2682
23 + 2659 = 2682
61 + 2621 = 2682
73 + 2609 = 2682
89 + 2593 = 2682
103 + 2579 = 2682

Showing the first eight; more decompositions exist.
