Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188366, here are decompositions:

7 + 188359 = 188366
43 + 188323 = 188366
67 + 188299 = 188366
223 + 188143 = 188366
229 + 188137 = 188366
337 + 188029 = 188366
349 + 188017 = 188366
379 + 187987 = 188366

Showing the first eight; more decompositions exist.
