Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28824, here are decompositions:
- 7 + 28817 = 28824
- 11 + 28813 = 28824
- 17 + 28807 = 28824
- 31 + 28793 = 28824
- 53 + 28771 = 28824
- 71 + 28753 = 28824
- 73 + 28751 = 28824
- 101 + 28723 = 28824
Showing the first eight; more decompositions exist.
