Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189404, here are decompositions:

3 + 189401 = 189404
13 + 189391 = 189404
43 + 189361 = 189404
67 + 189337 = 189404
97 + 189307 = 189404
151 + 189253 = 189404
181 + 189223 = 189404
277 + 189127 = 189404

Showing the first eight; more decompositions exist.
