Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189258, here are decompositions:

5 + 189253 = 189258
7 + 189251 = 189258
19 + 189239 = 189258
29 + 189229 = 189258
59 + 189199 = 189258
71 + 189187 = 189258
89 + 189169 = 189258
107 + 189151 = 189258

Showing the first eight; more decompositions exist.
