Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667138, here are decompositions:
- 17 + 8667121 = 8667138
- 59 + 8667079 = 8667138
- 149 + 8666989 = 8667138
- 199 + 8666939 = 8667138
- 211 + 8666927 = 8667138
- 257 + 8666881 = 8667138
- 331 + 8666807 = 8667138
- 457 + 8666681 = 8667138
Showing the first eight; more decompositions exist.
