Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186972, here are decompositions:

13 + 186959 = 186972
83 + 186889 = 186972
89 + 186883 = 186972
101 + 186871 = 186972
103 + 186869 = 186972
113 + 186859 = 186972
131 + 186841 = 186972
173 + 186799 = 186972

Showing the first eight; more decompositions exist.
