Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186842, here are decompositions:

43 + 186799 = 186842
79 + 186763 = 186842
109 + 186733 = 186842
163 + 186679 = 186842
193 + 186649 = 186842
223 + 186619 = 186842
241 + 186601 = 186842
373 + 186469 = 186842

Showing the first eight; more decompositions exist.
