Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47890, here are decompositions:
- 47 + 47843 = 47890
- 53 + 47837 = 47890
- 71 + 47819 = 47890
- 83 + 47807 = 47890
- 113 + 47777 = 47890
- 149 + 47741 = 47890
- 173 + 47717 = 47890
- 179 + 47711 = 47890
Showing the first eight; more decompositions exist.
