Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13682, here are decompositions:

3 + 13679 = 13682
13 + 13669 = 13682
241 + 13441 = 13682
271 + 13411 = 13682
283 + 13399 = 13682
373 + 13309 = 13682
433 + 13249 = 13682
463 + 13219 = 13682

Showing the first eight; more decompositions exist.
