Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18682, here are decompositions:

3 + 18679 = 18682
11 + 18671 = 18682
89 + 18593 = 18682
179 + 18503 = 18682
239 + 18443 = 18682
269 + 18413 = 18682
281 + 18401 = 18682
311 + 18371 = 18682

Showing the first eight; more decompositions exist.
