Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668142, here are decompositions:
- 31 + 8668111 = 8668142
- 61 + 8668081 = 8668142
- 79 + 8668063 = 8668142
- 163 + 8667979 = 8668142
- 181 + 8667961 = 8668142
- 193 + 8667949 = 8668142
- 211 + 8667931 = 8668142
- 229 + 8667913 = 8668142
Showing the first eight; more decompositions exist.
