Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20066, here are decompositions:
- 3 + 20063 = 20066
- 19 + 20047 = 20066
- 37 + 20029 = 20066
- 43 + 20023 = 20066
- 73 + 19993 = 20066
- 103 + 19963 = 20066
- 139 + 19927 = 20066
- 199 + 19867 = 20066
Showing the first eight; more decompositions exist.
