Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186996, here are decompositions:

37 + 186959 = 186996
79 + 186917 = 186996
107 + 186889 = 186996
113 + 186883 = 186996
127 + 186869 = 186996
137 + 186859 = 186996
197 + 186799 = 186996
223 + 186773 = 186996

Showing the first eight; more decompositions exist.
