Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18982, here are decompositions:
- 3 + 18979 = 18982
- 23 + 18959 = 18982
- 71 + 18911 = 18982
- 83 + 18899 = 18982
- 113 + 18869 = 18982
- 179 + 18803 = 18982
- 233 + 18749 = 18982
- 239 + 18743 = 18982
Showing the first eight; more decompositions exist.
