Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17980, here are decompositions:
- 3 + 17977 = 17980
- 23 + 17957 = 17980
- 41 + 17939 = 17980
- 59 + 17921 = 17980
- 71 + 17909 = 17980
- 89 + 17891 = 17980
- 173 + 17807 = 17980
- 191 + 17789 = 17980
Showing the first eight; more decompositions exist.
