Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609940, here are decompositions:
- 13 + 8609927 = 8609940
- 23 + 8609917 = 8609940
- 29 + 8609911 = 8609940
- 41 + 8609899 = 8609940
- 61 + 8609879 = 8609940
- 107 + 8609833 = 8609940
- 127 + 8609813 = 8609940
- 149 + 8609791 = 8609940
Showing the first eight; more decompositions exist.
