Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20288, here are decompositions:

19 + 20269 = 20288
127 + 20161 = 20288
139 + 20149 = 20288
181 + 20107 = 20288
199 + 20089 = 20288
241 + 20047 = 20288
277 + 20011 = 20288
397 + 19891 = 20288

Showing the first eight; more decompositions exist.
