Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7474, here are decompositions:
- 17 + 7457 = 7474
- 23 + 7451 = 7474
- 41 + 7433 = 7474
- 167 + 7307 = 7474
- 191 + 7283 = 7474
- 227 + 7247 = 7474
- 263 + 7211 = 7474
- 281 + 7193 = 7474
Showing the first eight; more decompositions exist.
