Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8408, here are decompositions:
- 19 + 8389 = 8408
- 31 + 8377 = 8408
- 79 + 8329 = 8408
- 97 + 8311 = 8408
- 139 + 8269 = 8408
- 199 + 8209 = 8408
- 229 + 8179 = 8408
- 241 + 8167 = 8408
Showing the first eight; more decompositions exist.
