Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971986, here are decompositions:

5 + 971981 = 971986
47 + 971939 = 971986
53 + 971933 = 971986
83 + 971903 = 971986
227 + 971759 = 971986
233 + 971753 = 971986
263 + 971723 = 971986
293 + 971693 = 971986

Showing the first eight; more decompositions exist.
