Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668040, here are decompositions:
- 61 + 8667979 = 8668040
- 67 + 8667973 = 8668040
- 79 + 8667961 = 8668040
- 109 + 8667931 = 8668040
- 127 + 8667913 = 8668040
- 193 + 8667847 = 8668040
- 211 + 8667829 = 8668040
- 307 + 8667733 = 8668040
Showing the first eight; more decompositions exist.
