Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189628, here are decompositions:

11 + 189617 = 189628
29 + 189599 = 189628
137 + 189491 = 189628
149 + 189479 = 189628
191 + 189437 = 189628
227 + 189401 = 189628
239 + 189389 = 189628
251 + 189377 = 189628

Showing the first eight; more decompositions exist.
