Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688750, here are decompositions:
- 11 + 8688739 = 8688750
- 43 + 8688707 = 8688750
- 47 + 8688703 = 8688750
- 53 + 8688697 = 8688750
- 79 + 8688671 = 8688750
- 137 + 8688613 = 8688750
- 139 + 8688611 = 8688750
- 149 + 8688601 = 8688750
Showing the first eight; more decompositions exist.
