Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84388, here are decompositions:

11 + 84377 = 84388
41 + 84347 = 84388
71 + 84317 = 84388
89 + 84299 = 84388
149 + 84239 = 84388
167 + 84221 = 84388
197 + 84191 = 84388
251 + 84137 = 84388

Showing the first eight; more decompositions exist.
