Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25864, here are decompositions:

17 + 25847 = 25864
23 + 25841 = 25864
71 + 25793 = 25864
101 + 25763 = 25864
131 + 25733 = 25864
191 + 25673 = 25864
197 + 25667 = 25864
263 + 25601 = 25864

Showing the first eight; more decompositions exist.
