Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7516, here are decompositions:
- 17 + 7499 = 7516
- 29 + 7487 = 7516
- 59 + 7457 = 7516
- 83 + 7433 = 7516
- 167 + 7349 = 7516
- 233 + 7283 = 7516
- 263 + 7253 = 7516
- 269 + 7247 = 7516
Showing the first eight; more decompositions exist.
