Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28716, here are decompositions:
- 5 + 28711 = 28716
- 13 + 28703 = 28716
- 19 + 28697 = 28716
- 29 + 28687 = 28716
- 47 + 28669 = 28716
- 53 + 28663 = 28716
- 59 + 28657 = 28716
- 67 + 28649 = 28716
Showing the first eight; more decompositions exist.
