Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25908, here are decompositions:

5 + 25903 = 25908
19 + 25889 = 25908
41 + 25867 = 25908
59 + 25849 = 25908
61 + 25847 = 25908
67 + 25841 = 25908
89 + 25819 = 25908
107 + 25801 = 25908

Showing the first eight; more decompositions exist.
