Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8398, here are decompositions:
- 11 + 8387 = 8398
- 29 + 8369 = 8398
- 101 + 8297 = 8398
- 107 + 8291 = 8398
- 167 + 8231 = 8398
- 179 + 8219 = 8398
- 227 + 8171 = 8398
- 251 + 8147 = 8398
Showing the first eight; more decompositions exist.
