Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28246, here are decompositions:
- 17 + 28229 = 28246
- 83 + 28163 = 28246
- 137 + 28109 = 28246
- 149 + 28097 = 28246
- 227 + 28019 = 28246
- 263 + 27983 = 28246
- 293 + 27953 = 28246
- 353 + 27893 = 28246
Showing the first eight; more decompositions exist.
