Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506, here are decompositions:
- 3 + 503 = 506
- 7 + 499 = 506
- 19 + 487 = 506
- 43 + 463 = 506
- 67 + 439 = 506
- 73 + 433 = 506
- 97 + 409 = 506
- 109 + 397 = 506
Showing the first eight; more decompositions exist.
