Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20526, here are decompositions:
- 5 + 20521 = 20526
- 17 + 20509 = 20526
- 19 + 20507 = 20526
- 43 + 20483 = 20526
- 47 + 20479 = 20526
- 83 + 20443 = 20526
- 127 + 20399 = 20526
- 137 + 20389 = 20526
Showing the first eight; more decompositions exist.
