Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71898, here are decompositions:
- 11 + 71887 = 71898
- 17 + 71881 = 71898
- 19 + 71879 = 71898
- 31 + 71867 = 71898
- 37 + 71861 = 71898
- 61 + 71837 = 71898
- 89 + 71809 = 71898
- 109 + 71789 = 71898
Showing the first eight; more decompositions exist.
