Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18002, here are decompositions:
- 13 + 17989 = 18002
- 31 + 17971 = 18002
- 43 + 17959 = 18002
- 73 + 17929 = 18002
- 79 + 17923 = 18002
- 139 + 17863 = 18002
- 151 + 17851 = 18002
- 163 + 17839 = 18002
Showing the first eight; more decompositions exist.
