Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189452, here are decompositions:

13 + 189439 = 189452
19 + 189433 = 189452
31 + 189421 = 189452
61 + 189391 = 189452
103 + 189349 = 189452
181 + 189271 = 189452
199 + 189253 = 189452
223 + 189229 = 189452

Showing the first eight; more decompositions exist.
