Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189494, here are decompositions:

3 + 189491 = 189494
31 + 189463 = 189494
61 + 189433 = 189494
73 + 189421 = 189494
103 + 189391 = 189494
157 + 189337 = 189494
223 + 189271 = 189494
241 + 189253 = 189494

Showing the first eight; more decompositions exist.
