Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6466, here are decompositions:
- 17 + 6449 = 6466
- 107 + 6359 = 6466
- 113 + 6353 = 6466
- 137 + 6329 = 6466
- 149 + 6317 = 6466
- 167 + 6299 = 6466
- 179 + 6287 = 6466
- 197 + 6269 = 6466
Showing the first eight; more decompositions exist.
