Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83786, here are decompositions:

13 + 83773 = 83786
67 + 83719 = 83786
97 + 83689 = 83786
223 + 83563 = 83786
229 + 83557 = 83786
337 + 83449 = 83786
349 + 83437 = 83786
379 + 83407 = 83786

Showing the first eight; more decompositions exist.
