Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468, here are decompositions:
- 5 + 463 = 468
- 7 + 461 = 468
- 11 + 457 = 468
- 19 + 449 = 468
- 29 + 439 = 468
- 37 + 431 = 468
- 47 + 421 = 468
- 59 + 409 = 468
Showing the first eight; more decompositions exist.
