Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20256, here are decompositions:

7 + 20249 = 20256
23 + 20233 = 20256
37 + 20219 = 20256
73 + 20183 = 20256
79 + 20177 = 20256
83 + 20173 = 20256
107 + 20149 = 20256
109 + 20147 = 20256

Showing the first eight; more decompositions exist.
