Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188344, here are decompositions:

11 + 188333 = 188344
41 + 188303 = 188344
53 + 188291 = 188344
71 + 188273 = 188344
83 + 188261 = 188344
173 + 188171 = 188344
197 + 188147 = 188344
461 + 187883 = 188344

Showing the first eight; more decompositions exist.
