Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25318, here are decompositions:

11 + 25307 = 25318
17 + 25301 = 25318
71 + 25247 = 25318
89 + 25229 = 25318
149 + 25169 = 25318
191 + 25127 = 25318
197 + 25121 = 25318
281 + 25037 = 25318

Showing the first eight; more decompositions exist.
