Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18804, here are decompositions:
- 7 + 18797 = 18804
- 11 + 18793 = 18804
- 17 + 18787 = 18804
- 31 + 18773 = 18804
- 47 + 18757 = 18804
- 61 + 18743 = 18804
- 73 + 18731 = 18804
- 103 + 18701 = 18804
Showing the first eight; more decompositions exist.
