Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47724, here are decompositions:
- 7 + 47717 = 47724
- 11 + 47713 = 47724
- 13 + 47711 = 47724
- 23 + 47701 = 47724
- 43 + 47681 = 47724
- 67 + 47657 = 47724
- 71 + 47653 = 47724
- 101 + 47623 = 47724
Showing the first eight; more decompositions exist.
