Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20022, here are decompositions:
- 11 + 20011 = 20022
- 29 + 19993 = 20022
- 31 + 19991 = 20022
- 43 + 19979 = 20022
- 59 + 19963 = 20022
- 61 + 19961 = 20022
- 73 + 19949 = 20022
- 103 + 19919 = 20022
Showing the first eight; more decompositions exist.
