Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667960, here are decompositions:
- 11 + 8667949 = 8667960
- 29 + 8667931 = 8667960
- 31 + 8667929 = 8667960
- 47 + 8667913 = 8667960
- 53 + 8667907 = 8667960
- 61 + 8667899 = 8667960
- 89 + 8667871 = 8667960
- 97 + 8667863 = 8667960
Showing the first eight; more decompositions exist.
