Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6512, here are decompositions:
- 31 + 6481 = 6512
- 43 + 6469 = 6512
- 61 + 6451 = 6512
- 139 + 6373 = 6512
- 151 + 6361 = 6512
- 211 + 6301 = 6512
- 241 + 6271 = 6512
- 283 + 6229 = 6512
Showing the first eight; more decompositions exist.
