Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516, here are decompositions:
- 7 + 509 = 516
- 13 + 503 = 516
- 17 + 499 = 516
- 29 + 487 = 516
- 37 + 479 = 516
- 53 + 463 = 516
- 59 + 457 = 516
- 67 + 449 = 516
Showing the first eight; more decompositions exist.
