Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86306, here are decompositions:

13 + 86293 = 86306
19 + 86287 = 86306
37 + 86269 = 86306
43 + 86263 = 86306
67 + 86239 = 86306
97 + 86209 = 86306
109 + 86197 = 86306
127 + 86179 = 86306

Showing the first eight; more decompositions exist.
