Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18000, here are decompositions:
- 11 + 17989 = 18000
- 13 + 17987 = 18000
- 19 + 17981 = 18000
- 23 + 17977 = 18000
- 29 + 17971 = 18000
- 41 + 17959 = 18000
- 43 + 17957 = 18000
- 61 + 17939 = 18000
Showing the first eight; more decompositions exist.
