Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28276, here are decompositions:

47 + 28229 = 28276
113 + 28163 = 28276
167 + 28109 = 28276
179 + 28097 = 28276
257 + 28019 = 28276
293 + 27983 = 28276
359 + 27917 = 28276
383 + 27893 = 28276

Showing the first eight; more decompositions exist.
