Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6456, here are decompositions:
- 5 + 6451 = 6456
- 7 + 6449 = 6456
- 29 + 6427 = 6456
- 59 + 6397 = 6456
- 67 + 6389 = 6456
- 83 + 6373 = 6456
- 89 + 6367 = 6456
- 97 + 6359 = 6456
Showing the first eight; more decompositions exist.
