Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47892, here are decompositions:
- 11 + 47881 = 47892
- 23 + 47869 = 47892
- 73 + 47819 = 47892
- 83 + 47809 = 47892
- 101 + 47791 = 47892
- 113 + 47779 = 47892
- 149 + 47743 = 47892
- 151 + 47741 = 47892
Showing the first eight; more decompositions exist.
