Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 466, here are decompositions:
- 3 + 463 = 466
- 5 + 461 = 466
- 17 + 449 = 466
- 23 + 443 = 466
- 47 + 419 = 466
- 83 + 383 = 466
- 107 + 359 = 466
- 113 + 353 = 466
Showing the first eight; more decompositions exist.
