Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71940, here are decompositions:
- 7 + 71933 = 71940
- 23 + 71917 = 71940
- 31 + 71909 = 71940
- 41 + 71899 = 71940
- 53 + 71887 = 71940
- 59 + 71881 = 71940
- 61 + 71879 = 71940
- 73 + 71867 = 71940
Showing the first eight; more decompositions exist.
