Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16972, here are decompositions:
- 29 + 16943 = 16972
- 41 + 16931 = 16972
- 71 + 16901 = 16972
- 83 + 16889 = 16972
- 89 + 16883 = 16972
- 101 + 16871 = 16972
- 149 + 16823 = 16972
- 269 + 16703 = 16972
Showing the first eight; more decompositions exist.
