Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18336, here are decompositions:
- 7 + 18329 = 18336
- 23 + 18313 = 18336
- 29 + 18307 = 18336
- 47 + 18289 = 18336
- 67 + 18269 = 18336
- 79 + 18257 = 18336
- 83 + 18253 = 18336
- 103 + 18233 = 18336
Showing the first eight; more decompositions exist.
