Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8104, here are decompositions:
- 3 + 8101 = 8104
- 11 + 8093 = 8104
- 17 + 8087 = 8104
- 23 + 8081 = 8104
- 167 + 7937 = 8104
- 197 + 7907 = 8104
- 227 + 7877 = 8104
- 251 + 7853 = 8104
Showing the first eight; more decompositions exist.
