Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28794, here are decompositions:
- 5 + 28789 = 28794
- 23 + 28771 = 28794
- 41 + 28753 = 28794
- 43 + 28751 = 28794
- 71 + 28723 = 28794
- 83 + 28711 = 28794
- 97 + 28697 = 28794
- 107 + 28687 = 28794
Showing the first eight; more decompositions exist.
