Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25888, here are decompositions:

41 + 25847 = 25888
47 + 25841 = 25888
89 + 25799 = 25888
311 + 25577 = 25888
347 + 25541 = 25888
419 + 25469 = 25888
431 + 25457 = 25888
449 + 25439 = 25888

Showing the first eight; more decompositions exist.
