Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18036, here are decompositions:
- 23 + 18013 = 18036
- 47 + 17989 = 18036
- 59 + 17977 = 18036
- 79 + 17957 = 18036
- 97 + 17939 = 18036
- 107 + 17929 = 18036
- 113 + 17923 = 18036
- 127 + 17909 = 18036
Showing the first eight; more decompositions exist.
