Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7318, here are decompositions:
- 11 + 7307 = 7318
- 71 + 7247 = 7318
- 89 + 7229 = 7318
- 107 + 7211 = 7318
- 131 + 7187 = 7318
- 167 + 7151 = 7318
- 191 + 7127 = 7318
- 197 + 7121 = 7318
Showing the first eight; more decompositions exist.
