Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188378, here are decompositions:

19 + 188359 = 188378
61 + 188317 = 188378
67 + 188311 = 188378
79 + 188299 = 188378
97 + 188281 = 188378
181 + 188197 = 188378
199 + 188179 = 188378
241 + 188137 = 188378

Showing the first eight; more decompositions exist.
