Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25386, here are decompositions:

13 + 25373 = 25386
19 + 25367 = 25386
29 + 25357 = 25386
37 + 25349 = 25386
43 + 25343 = 25386
47 + 25339 = 25386
79 + 25307 = 25386
83 + 25303 = 25386

Showing the first eight; more decompositions exist.
