Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71968, here are decompositions:
- 5 + 71963 = 71968
- 59 + 71909 = 71968
- 89 + 71879 = 71968
- 101 + 71867 = 71968
- 107 + 71861 = 71968
- 131 + 71837 = 71968
- 179 + 71789 = 71968
- 191 + 71777 = 71968
Showing the first eight; more decompositions exist.
