Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18894, here are decompositions:
- 97 + 18797 = 18894
- 101 + 18793 = 18894
- 107 + 18787 = 18894
- 137 + 18757 = 18894
- 151 + 18743 = 18894
- 163 + 18731 = 18894
- 181 + 18713 = 18894
- 193 + 18701 = 18894
Showing the first eight; more decompositions exist.
