Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189286, here are decompositions:

29 + 189257 = 189286
47 + 189239 = 189286
137 + 189149 = 189286
269 + 189017 = 189286
347 + 188939 = 189286
353 + 188933 = 189286
359 + 188927 = 189286
443 + 188843 = 189286

Showing the first eight; more decompositions exist.
