Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28848, here are decompositions:
- 5 + 28843 = 28848
- 11 + 28837 = 28848
- 31 + 28817 = 28848
- 41 + 28807 = 28848
- 59 + 28789 = 28848
- 89 + 28759 = 28848
- 97 + 28751 = 28848
- 137 + 28711 = 28848
Showing the first eight; more decompositions exist.
