Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6536, here are decompositions:
- 7 + 6529 = 6536
- 67 + 6469 = 6536
- 109 + 6427 = 6536
- 139 + 6397 = 6536
- 157 + 6379 = 6536
- 163 + 6373 = 6536
- 193 + 6343 = 6536
- 199 + 6337 = 6536
Showing the first eight; more decompositions exist.
