Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28108, here are decompositions:
- 11 + 28097 = 28108
- 89 + 28019 = 28108
- 107 + 28001 = 28108
- 167 + 27941 = 28108
- 191 + 27917 = 28108
- 257 + 27851 = 28108
- 281 + 27827 = 28108
- 317 + 27791 = 28108
Showing the first eight; more decompositions exist.
