Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25306, here are decompositions:

3 + 25303 = 25306
5 + 25301 = 25306
53 + 25253 = 25306
59 + 25247 = 25306
137 + 25169 = 25306
179 + 25127 = 25306
233 + 25073 = 25306
269 + 25037 = 25306

Showing the first eight; more decompositions exist.
