Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188844, here are decompositions:

11 + 188833 = 188844
13 + 188831 = 188844
17 + 188827 = 188844
43 + 188801 = 188844
53 + 188791 = 188844
137 + 188707 = 188844
151 + 188693 = 188844
157 + 188687 = 188844

Showing the first eight; more decompositions exist.
