Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47748, here are decompositions:
- 5 + 47743 = 47748
- 7 + 47741 = 47748
- 11 + 47737 = 47748
- 31 + 47717 = 47748
- 37 + 47711 = 47748
- 47 + 47701 = 47748
- 67 + 47681 = 47748
- 89 + 47659 = 47748
Showing the first eight; more decompositions exist.
