Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28300, here are decompositions:
- 3 + 28297 = 28300
- 11 + 28289 = 28300
- 17 + 28283 = 28300
- 23 + 28277 = 28300
- 71 + 28229 = 28300
- 89 + 28211 = 28300
- 137 + 28163 = 28300
- 149 + 28151 = 28300
Showing the first eight; more decompositions exist.
