Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6408, here are decompositions:
- 11 + 6397 = 6408
- 19 + 6389 = 6408
- 29 + 6379 = 6408
- 41 + 6367 = 6408
- 47 + 6361 = 6408
- 71 + 6337 = 6408
- 79 + 6329 = 6408
- 97 + 6311 = 6408
Showing the first eight; more decompositions exist.
