Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28268, here are decompositions:
- 67 + 28201 = 28268
- 157 + 28111 = 28268
- 181 + 28087 = 28268
- 199 + 28069 = 28268
- 211 + 28057 = 28268
- 241 + 28027 = 28268
- 271 + 27997 = 28268
- 307 + 27961 = 28268
Showing the first eight; more decompositions exist.
