Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8198, here are decompositions:
- 7 + 8191 = 8198
- 19 + 8179 = 8198
- 31 + 8167 = 8198
- 37 + 8161 = 8198
- 97 + 8101 = 8198
- 109 + 8089 = 8198
- 139 + 8059 = 8198
- 181 + 8017 = 8198
Showing the first eight; more decompositions exist.
