Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188288, here are decompositions:

7 + 188281 = 188288
109 + 188179 = 188288
151 + 188137 = 188288
181 + 188107 = 188288
271 + 188017 = 188288
277 + 188011 = 188288
337 + 187951 = 188288
367 + 187921 = 188288

Showing the first eight; more decompositions exist.
