Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188208, here are decompositions:

11 + 188197 = 188208
19 + 188189 = 188208
29 + 188179 = 188208
37 + 188171 = 188208
61 + 188147 = 188208
71 + 188137 = 188208
101 + 188107 = 188208
179 + 188029 = 188208

Showing the first eight; more decompositions exist.
