Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28814, here are decompositions:
- 7 + 28807 = 28814
- 43 + 28771 = 28814
- 61 + 28753 = 28814
- 103 + 28711 = 28814
- 127 + 28687 = 28814
- 151 + 28663 = 28814
- 157 + 28657 = 28814
- 193 + 28621 = 28814
Showing the first eight; more decompositions exist.
