Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25966, here are decompositions:

23 + 25943 = 25966
47 + 25919 = 25966
53 + 25913 = 25966
167 + 25799 = 25966
173 + 25793 = 25966
233 + 25733 = 25966
263 + 25703 = 25966
293 + 25673 = 25966

Showing the first eight; more decompositions exist.
