Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28426, here are decompositions:

17 + 28409 = 28426
23 + 28403 = 28426
107 + 28319 = 28426
137 + 28289 = 28426
149 + 28277 = 28426
197 + 28229 = 28426
263 + 28163 = 28426
317 + 28109 = 28426

Showing the first eight; more decompositions exist.
