Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71928, here are decompositions:
- 11 + 71917 = 71928
- 19 + 71909 = 71928
- 29 + 71899 = 71928
- 41 + 71887 = 71928
- 47 + 71881 = 71928
- 61 + 71867 = 71928
- 67 + 71861 = 71928
- 79 + 71849 = 71928
Showing the first eight; more decompositions exist.
