Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12832, here are decompositions:

3 + 12829 = 12832
11 + 12821 = 12832
23 + 12809 = 12832
41 + 12791 = 12832
89 + 12743 = 12832
173 + 12659 = 12832
179 + 12653 = 12832
191 + 12641 = 12832

Showing the first eight; more decompositions exist.
