Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 514, here are decompositions:
- 5 + 509 = 514
- 11 + 503 = 514
- 23 + 491 = 514
- 47 + 467 = 514
- 53 + 461 = 514
- 71 + 443 = 514
- 83 + 431 = 514
- 113 + 401 = 514
Showing the first eight; more decompositions exist.
