Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13140, here are decompositions:
- 13 + 13127 = 13140
- 19 + 13121 = 13140
- 31 + 13109 = 13140
- 37 + 13103 = 13140
- 41 + 13099 = 13140
- 47 + 13093 = 13140
- 97 + 13043 = 13140
- 103 + 13037 = 13140
Showing the first eight; more decompositions exist.
