Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020828, here are decompositions:
- 5 + 1020823 = 1020828
- 7 + 1020821 = 1020828
- 31 + 1020797 = 1020828
- 71 + 1020757 = 1020828
- 139 + 1020689 = 1020828
- 197 + 1020631 = 1020828
- 229 + 1020599 = 1020828
- 239 + 1020589 = 1020828
Showing the first eight; more decompositions exist.
