Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667990, here are decompositions:
- 11 + 8667979 = 8667990
- 17 + 8667973 = 8667990
- 29 + 8667961 = 8667990
- 41 + 8667949 = 8667990
- 59 + 8667931 = 8667990
- 61 + 8667929 = 8667990
- 83 + 8667907 = 8667990
- 127 + 8667863 = 8667990
Showing the first eight; more decompositions exist.
