Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666940, here are decompositions:
- 13 + 8666927 = 8666940
- 59 + 8666881 = 8666940
- 101 + 8666839 = 8666940
- 131 + 8666809 = 8666940
- 157 + 8666783 = 8666940
- 167 + 8666773 = 8666940
- 173 + 8666767 = 8666940
- 193 + 8666747 = 8666940
Showing the first eight; more decompositions exist.
