Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38666, here are decompositions:

13 + 38653 = 38666
37 + 38629 = 38666
73 + 38593 = 38666
97 + 38569 = 38666
109 + 38557 = 38666
337 + 38329 = 38666
349 + 38317 = 38666
367 + 38299 = 38666

Showing the first eight; more decompositions exist.
