Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6216, here are decompositions:
- 5 + 6211 = 6216
- 13 + 6203 = 6216
- 17 + 6199 = 6216
- 19 + 6197 = 6216
- 43 + 6173 = 6216
- 53 + 6163 = 6216
- 73 + 6143 = 6216
- 83 + 6133 = 6216
Showing the first eight; more decompositions exist.
