Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18048, here are decompositions:
- 5 + 18043 = 18048
- 7 + 18041 = 18048
- 59 + 17989 = 18048
- 61 + 17987 = 18048
- 67 + 17981 = 18048
- 71 + 17977 = 18048
- 89 + 17959 = 18048
- 109 + 17939 = 18048
Showing the first eight; more decompositions exist.
