Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20562, here are decompositions:
- 11 + 20551 = 20562
- 13 + 20549 = 20562
- 19 + 20543 = 20562
- 29 + 20533 = 20562
- 41 + 20521 = 20562
- 53 + 20509 = 20562
- 79 + 20483 = 20562
- 83 + 20479 = 20562
Showing the first eight; more decompositions exist.
