Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7308, here are decompositions:
- 11 + 7297 = 7308
- 61 + 7247 = 7308
- 71 + 7237 = 7308
- 79 + 7229 = 7308
- 89 + 7219 = 7308
- 97 + 7211 = 7308
- 101 + 7207 = 7308
- 131 + 7177 = 7308
Showing the first eight; more decompositions exist.
