Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71140, here are decompositions:
- 11 + 71129 = 71140
- 59 + 71081 = 71140
- 71 + 71069 = 71140
- 101 + 71039 = 71140
- 149 + 70991 = 71140
- 191 + 70949 = 71140
- 227 + 70913 = 71140
- 239 + 70901 = 71140
Showing the first eight; more decompositions exist.
