Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165616, here are decompositions:
- 5 + 165611 = 165616
- 29 + 165587 = 165616
- 47 + 165569 = 165616
- 83 + 165533 = 165616
- 89 + 165527 = 165616
- 137 + 165479 = 165616
- 167 + 165449 = 165616
- 173 + 165443 = 165616
Showing the first eight; more decompositions exist.
