Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47664, here are decompositions:
- 5 + 47659 = 47664
- 7 + 47657 = 47664
- 11 + 47653 = 47664
- 41 + 47623 = 47664
- 73 + 47591 = 47664
- 83 + 47581 = 47664
- 101 + 47563 = 47664
- 131 + 47533 = 47664
Showing the first eight; more decompositions exist.
