Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6426, here are decompositions:
- 5 + 6421 = 6426
- 29 + 6397 = 6426
- 37 + 6389 = 6426
- 47 + 6379 = 6426
- 53 + 6373 = 6426
- 59 + 6367 = 6426
- 67 + 6359 = 6426
- 73 + 6353 = 6426
Showing the first eight; more decompositions exist.
