Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28842, here are decompositions:
- 5 + 28837 = 28842
- 29 + 28813 = 28842
- 53 + 28789 = 28842
- 71 + 28771 = 28842
- 83 + 28759 = 28842
- 89 + 28753 = 28842
- 113 + 28729 = 28842
- 131 + 28711 = 28842
Showing the first eight; more decompositions exist.
