Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667840, here are decompositions:
- 11 + 8667829 = 8667840
- 19 + 8667821 = 8667840
- 31 + 8667809 = 8667840
- 43 + 8667797 = 8667840
- 47 + 8667793 = 8667840
- 107 + 8667733 = 8667840
- 113 + 8667727 = 8667840
- 151 + 8667689 = 8667840
Showing the first eight; more decompositions exist.
