Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83666, here are decompositions:

3 + 83663 = 83666
13 + 83653 = 83666
103 + 83563 = 83666
109 + 83557 = 83666
223 + 83443 = 83666
229 + 83437 = 83666
277 + 83389 = 83666
283 + 83383 = 83666

Showing the first eight; more decompositions exist.
