Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71964, here are decompositions:
- 17 + 71947 = 71964
- 23 + 71941 = 71964
- 31 + 71933 = 71964
- 47 + 71917 = 71964
- 83 + 71881 = 71964
- 97 + 71867 = 71964
- 103 + 71861 = 71964
- 127 + 71837 = 71964
Showing the first eight; more decompositions exist.
