Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18086, here are decompositions:
- 37 + 18049 = 18086
- 43 + 18043 = 18086
- 73 + 18013 = 18086
- 97 + 17989 = 18086
- 109 + 17977 = 18086
- 127 + 17959 = 18086
- 157 + 17929 = 18086
- 163 + 17923 = 18086
Showing the first eight; more decompositions exist.
