Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186900, here are decompositions:

11 + 186889 = 186900
17 + 186883 = 186900
23 + 186877 = 186900
29 + 186871 = 186900
31 + 186869 = 186900
41 + 186859 = 186900
59 + 186841 = 186900
101 + 186799 = 186900

Showing the first eight; more decompositions exist.
