Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47866, here are decompositions:
- 23 + 47843 = 47866
- 29 + 47837 = 47866
- 47 + 47819 = 47866
- 59 + 47807 = 47866
- 89 + 47777 = 47866
- 149 + 47717 = 47866
- 167 + 47699 = 47866
- 227 + 47639 = 47866
Showing the first eight; more decompositions exist.
