Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25982, here are decompositions:

13 + 25969 = 25982
31 + 25951 = 25982
43 + 25939 = 25982
79 + 25903 = 25982
109 + 25873 = 25982
163 + 25819 = 25982
181 + 25801 = 25982
211 + 25771 = 25982

Showing the first eight; more decompositions exist.
