Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16980, here are decompositions:
- 17 + 16963 = 16980
- 37 + 16943 = 16980
- 43 + 16937 = 16980
- 53 + 16927 = 16980
- 59 + 16921 = 16980
- 79 + 16901 = 16980
- 97 + 16883 = 16980
- 101 + 16879 = 16980
Showing the first eight; more decompositions exist.
