Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188192, here are decompositions:

3 + 188189 = 188192
13 + 188179 = 188192
163 + 188029 = 188192
181 + 188011 = 188192
229 + 187963 = 188192
241 + 187951 = 188192
271 + 187921 = 188192
283 + 187909 = 188192

Showing the first eight; more decompositions exist.
