Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25216, here are decompositions:

47 + 25169 = 25216
53 + 25163 = 25216
89 + 25127 = 25216
179 + 25037 = 25216
227 + 24989 = 25216
239 + 24977 = 25216
263 + 24953 = 25216
293 + 24923 = 25216

Showing the first eight; more decompositions exist.
