Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47730, here are decompositions:
- 13 + 47717 = 47730
- 17 + 47713 = 47730
- 19 + 47711 = 47730
- 29 + 47701 = 47730
- 31 + 47699 = 47730
- 71 + 47659 = 47730
- 73 + 47657 = 47730
- 101 + 47629 = 47730
Showing the first eight; more decompositions exist.
