Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25464, here are decompositions:

7 + 25457 = 25464
11 + 25453 = 25464
17 + 25447 = 25464
41 + 25423 = 25464
53 + 25411 = 25464
73 + 25391 = 25464
97 + 25367 = 25464
107 + 25357 = 25464

Showing the first eight; more decompositions exist.
