Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28836, here are decompositions:
- 19 + 28817 = 28836
- 23 + 28813 = 28836
- 29 + 28807 = 28836
- 43 + 28793 = 28836
- 47 + 28789 = 28836
- 83 + 28753 = 28836
- 107 + 28729 = 28836
- 113 + 28723 = 28836
Showing the first eight; more decompositions exist.
