Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722938, here are decompositions:
- 47 + 8722891 = 8722938
- 61 + 8722877 = 8722938
- 79 + 8722859 = 8722938
- 97 + 8722841 = 8722938
- 109 + 8722829 = 8722938
- 139 + 8722799 = 8722938
- 149 + 8722789 = 8722938
- 181 + 8722757 = 8722938
Showing the first eight; more decompositions exist.
