Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26866, here are decompositions:

3 + 26863 = 26866
5 + 26861 = 26866
17 + 26849 = 26866
53 + 26813 = 26866
83 + 26783 = 26866
89 + 26777 = 26866
107 + 26759 = 26866
137 + 26729 = 26866

Showing the first eight; more decompositions exist.
