Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71080, here are decompositions:
- 11 + 71069 = 71080
- 41 + 71039 = 71080
- 83 + 70997 = 71080
- 89 + 70991 = 71080
- 101 + 70979 = 71080
- 131 + 70949 = 71080
- 167 + 70913 = 71080
- 179 + 70901 = 71080
Showing the first eight; more decompositions exist.
