Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12982, here are decompositions:
- 3 + 12979 = 12982
- 23 + 12959 = 12982
- 29 + 12953 = 12982
- 41 + 12941 = 12982
- 59 + 12923 = 12982
- 71 + 12911 = 12982
- 83 + 12899 = 12982
- 89 + 12893 = 12982
Showing the first eight; more decompositions exist.
