Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25942, here are decompositions:

3 + 25939 = 25942
11 + 25931 = 25942
23 + 25919 = 25942
29 + 25913 = 25942
53 + 25889 = 25942
101 + 25841 = 25942
149 + 25793 = 25942
179 + 25763 = 25942

Showing the first eight; more decompositions exist.
