Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28682, here are decompositions:

13 + 28669 = 28682
19 + 28663 = 28682
61 + 28621 = 28682
79 + 28603 = 28682
103 + 28579 = 28682
109 + 28573 = 28682
271 + 28411 = 28682
331 + 28351 = 28682

Showing the first eight; more decompositions exist.
