Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13066, here are decompositions:
- 3 + 13063 = 13066
- 17 + 13049 = 13066
- 23 + 13043 = 13066
- 29 + 13037 = 13066
- 59 + 13007 = 13066
- 83 + 12983 = 13066
- 107 + 12959 = 13066
- 113 + 12953 = 13066
Showing the first eight; more decompositions exist.
