Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25470, here are decompositions:

7 + 25463 = 25470
13 + 25457 = 25470
17 + 25453 = 25470
23 + 25447 = 25470
31 + 25439 = 25470
47 + 25423 = 25470
59 + 25411 = 25470
61 + 25409 = 25470

Showing the first eight; more decompositions exist.
