Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28366, here are decompositions:
- 17 + 28349 = 28366
- 47 + 28319 = 28366
- 59 + 28307 = 28366
- 83 + 28283 = 28366
- 89 + 28277 = 28366
- 137 + 28229 = 28366
- 257 + 28109 = 28366
- 269 + 28097 = 28366
Showing the first eight; more decompositions exist.
