Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18264, here are decompositions:
- 7 + 18257 = 18264
- 11 + 18253 = 18264
- 13 + 18251 = 18264
- 31 + 18233 = 18264
- 41 + 18223 = 18264
- 47 + 18217 = 18264
- 53 + 18211 = 18264
- 73 + 18191 = 18264
Showing the first eight; more decompositions exist.
