Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28216, here are decompositions:
- 5 + 28211 = 28216
- 53 + 28163 = 28216
- 107 + 28109 = 28216
- 197 + 28019 = 28216
- 233 + 27983 = 28216
- 263 + 27953 = 28216
- 269 + 27947 = 28216
- 389 + 27827 = 28216
Showing the first eight; more decompositions exist.
