Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189384, here are decompositions:

7 + 189377 = 189384
23 + 189361 = 189384
31 + 189353 = 189384
37 + 189347 = 189384
47 + 189337 = 189384
73 + 189311 = 189384
113 + 189271 = 189384
127 + 189257 = 189384

Showing the first eight; more decompositions exist.
