Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020768, here are decompositions:
- 11 + 1020757 = 1020768
- 17 + 1020751 = 1020768
- 59 + 1020709 = 1020768
- 61 + 1020707 = 1020768
- 79 + 1020689 = 1020768
- 101 + 1020667 = 1020768
- 137 + 1020631 = 1020768
- 149 + 1020619 = 1020768
Showing the first eight; more decompositions exist.
