Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20026, here are decompositions:
- 3 + 20023 = 20026
- 5 + 20021 = 20026
- 29 + 19997 = 20026
- 47 + 19979 = 20026
- 53 + 19973 = 20026
- 89 + 19937 = 20026
- 107 + 19919 = 20026
- 113 + 19913 = 20026
Showing the first eight; more decompositions exist.
