Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19582, here are decompositions:

5 + 19577 = 19582
11 + 19571 = 19582
23 + 19559 = 19582
29 + 19553 = 19582
41 + 19541 = 19582
113 + 19469 = 19582
149 + 19433 = 19582
179 + 19403 = 19582

Showing the first eight; more decompositions exist.
