Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16938, here are decompositions:
- 7 + 16931 = 16938
- 11 + 16927 = 16938
- 17 + 16921 = 16938
- 37 + 16901 = 16938
- 59 + 16879 = 16938
- 67 + 16871 = 16938
- 107 + 16831 = 16938
- 109 + 16829 = 16938
Showing the first eight; more decompositions exist.
