Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28798, here are decompositions:
- 5 + 28793 = 28798
- 47 + 28751 = 28798
- 101 + 28697 = 28798
- 137 + 28661 = 28798
- 149 + 28649 = 28798
- 167 + 28631 = 28798
- 179 + 28619 = 28798
- 191 + 28607 = 28798
Showing the first eight; more decompositions exist.
