Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715918, here are decompositions:
- 11 + 8715907 = 8715918
- 17 + 8715901 = 8715918
- 31 + 8715887 = 8715918
- 37 + 8715881 = 8715918
- 41 + 8715877 = 8715918
- 131 + 8715787 = 8715918
- 139 + 8715779 = 8715918
- 149 + 8715769 = 8715918
Showing the first eight; more decompositions exist.
