Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25918, here are decompositions:

5 + 25913 = 25918
29 + 25889 = 25918
71 + 25847 = 25918
239 + 25679 = 25918
251 + 25667 = 25918
317 + 25601 = 25918
449 + 25469 = 25918
461 + 25457 = 25918

Showing the first eight; more decompositions exist.
