Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722896, here are decompositions:
- 5 + 8722891 = 8722896
- 19 + 8722877 = 8722896
- 37 + 8722859 = 8722896
- 67 + 8722829 = 8722896
- 97 + 8722799 = 8722896
- 107 + 8722789 = 8722896
- 139 + 8722757 = 8722896
- 157 + 8722739 = 8722896
Showing the first eight; more decompositions exist.
