Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25408, here are decompositions:

17 + 25391 = 25408
41 + 25367 = 25408
59 + 25349 = 25408
101 + 25307 = 25408
107 + 25301 = 25408
179 + 25229 = 25408
239 + 25169 = 25408
281 + 25127 = 25408

Showing the first eight; more decompositions exist.
