Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18258, here are decompositions:
- 5 + 18253 = 18258
- 7 + 18251 = 18258
- 29 + 18229 = 18258
- 41 + 18217 = 18258
- 47 + 18211 = 18258
- 59 + 18199 = 18258
- 67 + 18191 = 18258
- 89 + 18169 = 18258
Showing the first eight; more decompositions exist.
