Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13006, here are decompositions:
- 3 + 13003 = 13006
- 5 + 13001 = 13006
- 23 + 12983 = 13006
- 47 + 12959 = 13006
- 53 + 12953 = 13006
- 83 + 12923 = 13006
- 89 + 12917 = 13006
- 107 + 12899 = 13006
Showing the first eight; more decompositions exist.
