Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7498, here are decompositions:
- 11 + 7487 = 7498
- 17 + 7481 = 7498
- 41 + 7457 = 7498
- 47 + 7451 = 7498
- 149 + 7349 = 7498
- 167 + 7331 = 7498
- 191 + 7307 = 7498
- 251 + 7247 = 7498
Showing the first eight; more decompositions exist.
