Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12858, here are decompositions:

5 + 12853 = 12858
17 + 12841 = 12858
29 + 12829 = 12858
37 + 12821 = 12858
59 + 12799 = 12858
67 + 12791 = 12858
101 + 12757 = 12858
137 + 12721 = 12858

Showing the first eight; more decompositions exist.
