Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013808, here are decompositions:
- 17 + 1013791 = 1013808
- 41 + 1013767 = 1013808
- 67 + 1013741 = 1013808
- 79 + 1013729 = 1013808
- 97 + 1013711 = 1013808
- 109 + 1013699 = 1013808
- 127 + 1013681 = 1013808
- 137 + 1013671 = 1013808
Showing the first eight; more decompositions exist.
