Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022, here are decompositions:
- 3 + 1019 = 1022
- 13 + 1009 = 1022
- 31 + 991 = 1022
- 103 + 919 = 1022
- 139 + 883 = 1022
- 163 + 859 = 1022
- 193 + 829 = 1022
- 199 + 823 = 1022
Showing the first eight; more decompositions exist.
