Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189554, here are decompositions:

7 + 189547 = 189554
31 + 189523 = 189554
37 + 189517 = 189554
61 + 189493 = 189554
163 + 189391 = 189554
193 + 189361 = 189554
283 + 189271 = 189554
331 + 189223 = 189554

Showing the first eight; more decompositions exist.
