Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17918, here are decompositions:
- 7 + 17911 = 17918
- 37 + 17881 = 17918
- 67 + 17851 = 17918
- 79 + 17839 = 17918
- 127 + 17791 = 17918
- 157 + 17761 = 17918
- 181 + 17737 = 17918
- 211 + 17707 = 17918
Showing the first eight; more decompositions exist.
