Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18364, here are decompositions:
- 11 + 18353 = 18364
- 23 + 18341 = 18364
- 53 + 18311 = 18364
- 107 + 18257 = 18364
- 113 + 18251 = 18364
- 131 + 18233 = 18364
- 173 + 18191 = 18364
- 233 + 18131 = 18364
Showing the first eight; more decompositions exist.
