Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47800, here are decompositions:
- 3 + 47797 = 47800
- 23 + 47777 = 47800
- 59 + 47741 = 47800
- 83 + 47717 = 47800
- 89 + 47711 = 47800
- 101 + 47699 = 47800
- 191 + 47609 = 47800
- 257 + 47543 = 47800
Showing the first eight; more decompositions exist.
