Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186664, here are decompositions:

11 + 186653 = 186664
17 + 186647 = 186664
83 + 186581 = 186664
113 + 186551 = 186664
227 + 186437 = 186664
347 + 186317 = 186664
353 + 186311 = 186664
503 + 186161 = 186664

Showing the first eight; more decompositions exist.
