Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25868, here are decompositions:

19 + 25849 = 25868
67 + 25801 = 25868
97 + 25771 = 25868
109 + 25759 = 25868
127 + 25741 = 25868
151 + 25717 = 25868
211 + 25657 = 25868
229 + 25639 = 25868

Showing the first eight; more decompositions exist.
