Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20502, here are decompositions:
- 19 + 20483 = 20502
- 23 + 20479 = 20502
- 59 + 20443 = 20502
- 61 + 20441 = 20502
- 71 + 20431 = 20502
- 103 + 20399 = 20502
- 109 + 20393 = 20502
- 113 + 20389 = 20502
Showing the first eight; more decompositions exist.
