Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472, here are decompositions:
- 5 + 467 = 472
- 11 + 461 = 472
- 23 + 449 = 472
- 29 + 443 = 472
- 41 + 431 = 472
- 53 + 419 = 472
- 71 + 401 = 472
- 83 + 389 = 472
Showing the first eight; more decompositions exist.
