Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188316, here are decompositions:

5 + 188311 = 188316
13 + 188303 = 188316
17 + 188299 = 188316
43 + 188273 = 188316
67 + 188249 = 188316
127 + 188189 = 188316
137 + 188179 = 188316
157 + 188159 = 188316

Showing the first eight; more decompositions exist.
