Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84108, here are decompositions:
- 19 + 84089 = 84108
- 41 + 84067 = 84108
- 47 + 84061 = 84108
- 61 + 84047 = 84108
- 97 + 84011 = 84108
- 139 + 83969 = 84108
- 197 + 83911 = 84108
- 239 + 83869 = 84108
Showing the first eight; more decompositions exist.
