Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26986, here are decompositions:

5 + 26981 = 26986
59 + 26927 = 26986
83 + 26903 = 26986
107 + 26879 = 26986
137 + 26849 = 26986
173 + 26813 = 26986
227 + 26759 = 26986
257 + 26729 = 26986

Showing the first eight; more decompositions exist.
