Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186906, here are decompositions:

17 + 186889 = 186906
23 + 186883 = 186906
29 + 186877 = 186906
37 + 186869 = 186906
47 + 186859 = 186906
107 + 186799 = 186906
113 + 186793 = 186906
149 + 186757 = 186906

Showing the first eight; more decompositions exist.
