Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464, here are decompositions:
- 3 + 461 = 464
- 7 + 457 = 464
- 31 + 433 = 464
- 43 + 421 = 464
- 67 + 397 = 464
- 97 + 367 = 464
- 127 + 337 = 464
- 151 + 313 = 464
Showing the first eight; more decompositions exist.
