Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18832, here are decompositions:
- 29 + 18803 = 18832
- 59 + 18773 = 18832
- 83 + 18749 = 18832
- 89 + 18743 = 18832
- 101 + 18731 = 18832
- 113 + 18719 = 18832
- 131 + 18701 = 18832
- 239 + 18593 = 18832
Showing the first eight; more decompositions exist.
