Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9520, here are decompositions:
- 23 + 9497 = 9520
- 29 + 9491 = 9520
- 41 + 9479 = 9520
- 47 + 9473 = 9520
- 53 + 9467 = 9520
- 59 + 9461 = 9520
- 83 + 9437 = 9520
- 89 + 9431 = 9520
Showing the first eight; more decompositions exist.
