Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7298, here are decompositions:
- 61 + 7237 = 7298
- 79 + 7219 = 7298
- 139 + 7159 = 7298
- 229 + 7069 = 7298
- 241 + 7057 = 7298
- 271 + 7027 = 7298
- 307 + 6991 = 7298
- 331 + 6967 = 7298
Showing the first eight; more decompositions exist.
