Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6516, here are decompositions:
- 43 + 6473 = 6516
- 47 + 6469 = 6516
- 67 + 6449 = 6516
- 89 + 6427 = 6516
- 127 + 6389 = 6516
- 137 + 6379 = 6516
- 149 + 6367 = 6516
- 157 + 6359 = 6516
Showing the first eight; more decompositions exist.
