Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28876, here are decompositions:
- 5 + 28871 = 28876
- 17 + 28859 = 28876
- 59 + 28817 = 28876
- 83 + 28793 = 28876
- 173 + 28703 = 28876
- 179 + 28697 = 28876
- 227 + 28649 = 28876
- 233 + 28643 = 28876
Showing the first eight; more decompositions exist.
