Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28294, here are decompositions:
- 5 + 28289 = 28294
- 11 + 28283 = 28294
- 17 + 28277 = 28294
- 83 + 28211 = 28294
- 113 + 28181 = 28294
- 131 + 28163 = 28294
- 197 + 28097 = 28294
- 263 + 28031 = 28294
Showing the first eight; more decompositions exist.
