Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82986, here are decompositions:

5 + 82981 = 82986
23 + 82963 = 82986
47 + 82939 = 82986
73 + 82913 = 82986
83 + 82903 = 82986
97 + 82889 = 82986
103 + 82883 = 82986
139 + 82847 = 82986

Showing the first eight; more decompositions exist.
