Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8516, here are decompositions:
- 3 + 8513 = 8516
- 73 + 8443 = 8516
- 97 + 8419 = 8516
- 127 + 8389 = 8516
- 139 + 8377 = 8516
- 163 + 8353 = 8516
- 199 + 8317 = 8516
- 223 + 8293 = 8516
Showing the first eight; more decompositions exist.
