Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 446, here are decompositions:
- 3 + 443 = 446
- 7 + 439 = 446
- 13 + 433 = 446
- 37 + 409 = 446
- 67 + 379 = 446
- 73 + 373 = 446
- 79 + 367 = 446
- 97 + 349 = 446
Showing the first eight; more decompositions exist.
