Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526, here are decompositions:
- 3 + 523 = 526
- 5 + 521 = 526
- 17 + 509 = 526
- 23 + 503 = 526
- 47 + 479 = 526
- 59 + 467 = 526
- 83 + 443 = 526
- 107 + 419 = 526
Showing the first eight; more decompositions exist.
