Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18004, here are decompositions:
- 17 + 17987 = 18004
- 23 + 17981 = 18004
- 47 + 17957 = 18004
- 83 + 17921 = 18004
- 101 + 17903 = 18004
- 113 + 17891 = 18004
- 167 + 17837 = 18004
- 197 + 17807 = 18004
Showing the first eight; more decompositions exist.
