Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003808, here are decompositions:
- 37 + 1003771 = 1003808
- 61 + 1003747 = 1003808
- 67 + 1003741 = 1003808
- 79 + 1003729 = 1003808
- 97 + 1003711 = 1003808
- 181 + 1003627 = 1003808
- 199 + 1003609 = 1003808
- 397 + 1003411 = 1003808
Showing the first eight; more decompositions exist.
