Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667140, here are decompositions:
- 3 + 8667137 = 8667140
- 19 + 8667121 = 8667140
- 37 + 8667103 = 8667140
- 61 + 8667079 = 8667140
- 151 + 8666989 = 8667140
- 277 + 8666863 = 8667140
- 331 + 8666809 = 8667140
- 367 + 8666773 = 8667140
Showing the first eight; more decompositions exist.
