Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20532, here are decompositions:
- 11 + 20521 = 20532
- 23 + 20509 = 20532
- 53 + 20479 = 20532
- 89 + 20443 = 20532
- 101 + 20431 = 20532
- 139 + 20393 = 20532
- 163 + 20369 = 20532
- 173 + 20359 = 20532
Showing the first eight; more decompositions exist.
