Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28894, here are decompositions:
- 23 + 28871 = 28894
- 101 + 28793 = 28894
- 191 + 28703 = 28894
- 197 + 28697 = 28894
- 233 + 28661 = 28894
- 251 + 28643 = 28894
- 263 + 28631 = 28894
- 347 + 28547 = 28894
Showing the first eight; more decompositions exist.
