Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28144, here are decompositions:

47 + 28097 = 28144
113 + 28031 = 28144
191 + 27953 = 28144
197 + 27947 = 28144
227 + 27917 = 28144
251 + 27893 = 28144
293 + 27851 = 28144
317 + 27827 = 28144

Showing the first eight; more decompositions exist.
