Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10216, here are decompositions:
- 5 + 10211 = 10216
- 23 + 10193 = 10216
- 47 + 10169 = 10216
- 53 + 10163 = 10216
- 83 + 10133 = 10216
- 113 + 10103 = 10216
- 137 + 10079 = 10216
- 149 + 10067 = 10216
Showing the first eight; more decompositions exist.
