Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13146, here are decompositions:
- 19 + 13127 = 13146
- 37 + 13109 = 13146
- 43 + 13103 = 13146
- 47 + 13099 = 13146
- 53 + 13093 = 13146
- 83 + 13063 = 13146
- 97 + 13049 = 13146
- 103 + 13043 = 13146
Showing the first eight; more decompositions exist.
