Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18934, here are decompositions:
- 17 + 18917 = 18934
- 23 + 18911 = 18934
- 131 + 18803 = 18934
- 137 + 18797 = 18934
- 191 + 18743 = 18934
- 233 + 18701 = 18934
- 263 + 18671 = 18934
- 317 + 18617 = 18934
Showing the first eight; more decompositions exist.
