Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25600, here are decompositions:

11 + 25589 = 25600
17 + 25583 = 25600
23 + 25577 = 25600
59 + 25541 = 25600
131 + 25469 = 25600
137 + 25463 = 25600
191 + 25409 = 25600
227 + 25373 = 25600

Showing the first eight; more decompositions exist.
