Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6464, here are decompositions:
- 13 + 6451 = 6464
- 37 + 6427 = 6464
- 43 + 6421 = 6464
- 67 + 6397 = 6464
- 97 + 6367 = 6464
- 103 + 6361 = 6464
- 127 + 6337 = 6464
- 163 + 6301 = 6464
Showing the first eight; more decompositions exist.
