Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20834, here are decompositions:
- 61 + 20773 = 20834
- 103 + 20731 = 20834
- 127 + 20707 = 20834
- 193 + 20641 = 20834
- 223 + 20611 = 20834
- 241 + 20593 = 20834
- 271 + 20563 = 20834
- 283 + 20551 = 20834
Showing the first eight; more decompositions exist.
