Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666998, here are decompositions:
- 5 + 8666993 = 8666998
- 59 + 8666939 = 8666998
- 71 + 8666927 = 8666998
- 107 + 8666891 = 8666998
- 149 + 8666849 = 8666998
- 191 + 8666807 = 8666998
- 251 + 8666747 = 8666998
- 317 + 8666681 = 8666998
Showing the first eight; more decompositions exist.
