Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189250, here are decompositions:

11 + 189239 = 189250
101 + 189149 = 189250
233 + 189017 = 189250
239 + 189011 = 189250
251 + 188999 = 189250
293 + 188957 = 189250
311 + 188939 = 189250
317 + 188933 = 189250

Showing the first eight; more decompositions exist.
