Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25200, here are decompositions:

11 + 25189 = 25200
17 + 25183 = 25200
29 + 25171 = 25200
31 + 25169 = 25200
37 + 25163 = 25200
47 + 25153 = 25200
53 + 25147 = 25200
73 + 25127 = 25200

Showing the first eight; more decompositions exist.
