Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71040, here are decompositions:
- 17 + 71023 = 71040
- 29 + 71011 = 71040
- 41 + 70999 = 71040
- 43 + 70997 = 71040
- 59 + 70981 = 71040
- 61 + 70979 = 71040
- 71 + 70969 = 71040
- 83 + 70957 = 71040
Showing the first eight; more decompositions exist.
