Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17586, here are decompositions:

5 + 17581 = 17586
7 + 17579 = 17586
13 + 17573 = 17586
17 + 17569 = 17586
47 + 17539 = 17586
67 + 17519 = 17586
89 + 17497 = 17586
97 + 17489 = 17586

Showing the first eight; more decompositions exist.
