Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47906, here are decompositions:
- 3 + 47903 = 47906
- 37 + 47869 = 47906
- 97 + 47809 = 47906
- 109 + 47797 = 47906
- 127 + 47779 = 47906
- 163 + 47743 = 47906
- 193 + 47713 = 47906
- 277 + 47629 = 47906
Showing the first eight; more decompositions exist.
