Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028808, here are decompositions:
- 5 + 1028803 = 1028808
- 31 + 1028777 = 1028808
- 47 + 1028761 = 1028808
- 59 + 1028749 = 1028808
- 61 + 1028747 = 1028808
- 71 + 1028737 = 1028808
- 127 + 1028681 = 1028808
- 139 + 1028669 = 1028808
Showing the first eight; more decompositions exist.
