Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189392, here are decompositions:

3 + 189389 = 189392
31 + 189361 = 189392
43 + 189349 = 189392
139 + 189253 = 189392
163 + 189229 = 189392
193 + 189199 = 189392
223 + 189169 = 189392
241 + 189151 = 189392

Showing the first eight; more decompositions exist.
