Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47740, here are decompositions:
- 3 + 47737 = 47740
- 23 + 47717 = 47740
- 29 + 47711 = 47740
- 41 + 47699 = 47740
- 59 + 47681 = 47740
- 83 + 47657 = 47740
- 101 + 47639 = 47740
- 131 + 47609 = 47740
Showing the first eight; more decompositions exist.
