Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188804, here are decompositions:

3 + 188801 = 188804
13 + 188791 = 188804
37 + 188767 = 188804
97 + 188707 = 188804
103 + 188701 = 188804
127 + 188677 = 188804
151 + 188653 = 188804
241 + 188563 = 188804

Showing the first eight; more decompositions exist.
