Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28474, here are decompositions:

11 + 28463 = 28474
41 + 28433 = 28474
71 + 28403 = 28474
167 + 28307 = 28474
191 + 28283 = 28474
197 + 28277 = 28474
263 + 28211 = 28474
293 + 28181 = 28474

Showing the first eight; more decompositions exist.
