Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188338, here are decompositions:

5 + 188333 = 188338
47 + 188291 = 188338
89 + 188249 = 188338
149 + 188189 = 188338
167 + 188171 = 188338
179 + 188159 = 188338
191 + 188147 = 188338
317 + 188021 = 188338

Showing the first eight; more decompositions exist.
