Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25884, here are decompositions:

11 + 25873 = 25884
17 + 25867 = 25884
37 + 25847 = 25884
43 + 25841 = 25884
83 + 25801 = 25884
113 + 25771 = 25884
137 + 25747 = 25884
151 + 25733 = 25884

Showing the first eight; more decompositions exist.
