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.
