Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 586, here are decompositions:
- 17 + 569 = 586
- 23 + 563 = 586
- 29 + 557 = 586
- 83 + 503 = 586
- 107 + 479 = 586
- 137 + 449 = 586
- 167 + 419 = 586
- 197 + 389 = 586
Showing the first eight; more decompositions exist.
