Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25458, here are decompositions:

5 + 25453 = 25458
11 + 25447 = 25458
19 + 25439 = 25458
47 + 25411 = 25458
67 + 25391 = 25458
101 + 25357 = 25458
109 + 25349 = 25458
137 + 25321 = 25458

Showing the first eight; more decompositions exist.
