Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8938, here are decompositions:
- 5 + 8933 = 8938
- 71 + 8867 = 8938
- 89 + 8849 = 8938
- 101 + 8837 = 8938
- 107 + 8831 = 8938
- 131 + 8807 = 8938
- 191 + 8747 = 8938
- 197 + 8741 = 8938
Showing the first eight; more decompositions exist.
