Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71892, here are decompositions:
- 5 + 71887 = 71892
- 11 + 71881 = 71892
- 13 + 71879 = 71892
- 31 + 71861 = 71892
- 43 + 71849 = 71892
- 71 + 71821 = 71892
- 83 + 71809 = 71892
- 103 + 71789 = 71892
Showing the first eight; more decompositions exist.
