Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189398, here are decompositions:

7 + 189391 = 189398
37 + 189361 = 189398
61 + 189337 = 189398
127 + 189271 = 189398
199 + 189199 = 189398
211 + 189187 = 189398
229 + 189169 = 189398
271 + 189127 = 189398

Showing the first eight; more decompositions exist.
