Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25006, here are decompositions:

17 + 24989 = 25006
29 + 24977 = 25006
53 + 24953 = 25006
83 + 24923 = 25006
89 + 24917 = 25006
197 + 24809 = 25006
239 + 24767 = 25006
257 + 24749 = 25006

Showing the first eight; more decompositions exist.
