Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16956, here are decompositions:
- 13 + 16943 = 16956
- 19 + 16937 = 16956
- 29 + 16927 = 16956
- 53 + 16903 = 16956
- 67 + 16889 = 16956
- 73 + 16883 = 16956
- 113 + 16843 = 16956
- 127 + 16829 = 16956
Showing the first eight; more decompositions exist.
