Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28372, here are decompositions:
- 23 + 28349 = 28372
- 53 + 28319 = 28372
- 83 + 28289 = 28372
- 89 + 28283 = 28372
- 191 + 28181 = 28372
- 263 + 28109 = 28372
- 353 + 28019 = 28372
- 389 + 27983 = 28372
Showing the first eight; more decompositions exist.
