Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47904, here are decompositions:
- 23 + 47881 = 47904
- 47 + 47857 = 47904
- 61 + 47843 = 47904
- 67 + 47837 = 47904
- 97 + 47807 = 47904
- 107 + 47797 = 47904
- 113 + 47791 = 47904
- 127 + 47777 = 47904
Showing the first eight; more decompositions exist.
