Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667750, here are decompositions:
- 17 + 8667733 = 8667750
- 23 + 8667727 = 8667750
- 29 + 8667721 = 8667750
- 43 + 8667707 = 8667750
- 53 + 8667697 = 8667750
- 61 + 8667689 = 8667750
- 73 + 8667677 = 8667750
- 89 + 8667661 = 8667750
Showing the first eight; more decompositions exist.
