Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186936, here are decompositions:

19 + 186917 = 186936
47 + 186889 = 186936
53 + 186883 = 186936
59 + 186877 = 186936
67 + 186869 = 186936
137 + 186799 = 186936
163 + 186773 = 186936
173 + 186763 = 186936

Showing the first eight; more decompositions exist.
