Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28336, here are decompositions:
- 17 + 28319 = 28336
- 29 + 28307 = 28336
- 47 + 28289 = 28336
- 53 + 28283 = 28336
- 59 + 28277 = 28336
- 107 + 28229 = 28336
- 173 + 28163 = 28336
- 227 + 28109 = 28336
Showing the first eight; more decompositions exist.
