Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25886, here are decompositions:

13 + 25873 = 25886
19 + 25867 = 25886
37 + 25849 = 25886
67 + 25819 = 25886
127 + 25759 = 25886
139 + 25747 = 25886
193 + 25693 = 25886
229 + 25657 = 25886

Showing the first eight; more decompositions exist.
