Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8194, here are decompositions:
- 3 + 8191 = 8194
- 23 + 8171 = 8194
- 47 + 8147 = 8194
- 71 + 8123 = 8194
- 83 + 8111 = 8194
- 101 + 8093 = 8194
- 107 + 8087 = 8194
- 113 + 8081 = 8194
Showing the first eight; more decompositions exist.
