Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25000, here are decompositions:

11 + 24989 = 25000
23 + 24977 = 25000
29 + 24971 = 25000
47 + 24953 = 25000
83 + 24917 = 25000
149 + 24851 = 25000
179 + 24821 = 25000
191 + 24809 = 25000

Showing the first eight; more decompositions exist.
