Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25986, here are decompositions:

5 + 25981 = 25986
17 + 25969 = 25986
43 + 25943 = 25986
47 + 25939 = 25986
53 + 25933 = 25986
67 + 25919 = 25986
73 + 25913 = 25986
83 + 25903 = 25986

Showing the first eight; more decompositions exist.
