Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25390, here are decompositions:

17 + 25373 = 25390
23 + 25367 = 25390
41 + 25349 = 25390
47 + 25343 = 25390
83 + 25307 = 25390
89 + 25301 = 25390
137 + 25253 = 25390
227 + 25163 = 25390

Showing the first eight; more decompositions exist.
