Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17988, here are decompositions:
- 7 + 17981 = 17988
- 11 + 17977 = 17988
- 17 + 17971 = 17988
- 29 + 17959 = 17988
- 31 + 17957 = 17988
- 59 + 17929 = 17988
- 67 + 17921 = 17988
- 79 + 17909 = 17988
Showing the first eight; more decompositions exist.
