Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32728, here are decompositions:

11 + 32717 = 32728
41 + 32687 = 32728
107 + 32621 = 32728
149 + 32579 = 32728
167 + 32561 = 32728
191 + 32537 = 32728
197 + 32531 = 32728
317 + 32411 = 32728

Showing the first eight; more decompositions exist.
