Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25724, here are decompositions:

7 + 25717 = 25724
31 + 25693 = 25724
67 + 25657 = 25724
103 + 25621 = 25724
163 + 25561 = 25724
271 + 25453 = 25724
277 + 25447 = 25724
313 + 25411 = 25724

Showing the first eight; more decompositions exist.
