Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11980, here are decompositions:
- 11 + 11969 = 11980
- 41 + 11939 = 11980
- 47 + 11933 = 11980
- 53 + 11927 = 11980
- 71 + 11909 = 11980
- 83 + 11897 = 11980
- 113 + 11867 = 11980
- 149 + 11831 = 11980
Showing the first eight; more decompositions exist.
