Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17520, here are decompositions:
- 11 + 17509 = 17520
- 23 + 17497 = 17520
- 29 + 17491 = 17520
- 31 + 17489 = 17520
- 37 + 17483 = 17520
- 43 + 17477 = 17520
- 53 + 17467 = 17520
- 71 + 17449 = 17520
Showing the first eight; more decompositions exist.
