Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667942, here are decompositions:
- 11 + 8667931 = 8667942
- 13 + 8667929 = 8667942
- 29 + 8667913 = 8667942
- 43 + 8667899 = 8667942
- 71 + 8667871 = 8667942
- 79 + 8667863 = 8667942
- 113 + 8667829 = 8667942
- 149 + 8667793 = 8667942
Showing the first eight; more decompositions exist.
