Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186956, here are decompositions:

67 + 186889 = 186956
73 + 186883 = 186956
79 + 186877 = 186956
97 + 186859 = 186956
157 + 186799 = 186956
163 + 186793 = 186956
193 + 186763 = 186956
199 + 186757 = 186956

Showing the first eight; more decompositions exist.
