Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189270, here are decompositions:

13 + 189257 = 189270
17 + 189253 = 189270
19 + 189251 = 189270
31 + 189239 = 189270
41 + 189229 = 189270
47 + 189223 = 189270
71 + 189199 = 189270
83 + 189187 = 189270

Showing the first eight; more decompositions exist.
