Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186948, here are decompositions:

31 + 186917 = 186948
59 + 186889 = 186948
71 + 186877 = 186948
79 + 186869 = 186948
89 + 186859 = 186948
107 + 186841 = 186948
149 + 186799 = 186948
191 + 186757 = 186948

Showing the first eight; more decompositions exist.
