Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80986, here are decompositions:

23 + 80963 = 80986
53 + 80933 = 80986
89 + 80897 = 80986
137 + 80849 = 80986
167 + 80819 = 80986
197 + 80789 = 80986
239 + 80747 = 80986
317 + 80669 = 80986

Showing the first eight; more decompositions exist.
