Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47928, here are decompositions:
- 11 + 47917 = 47928
- 17 + 47911 = 47928
- 47 + 47881 = 47928
- 59 + 47869 = 47928
- 71 + 47857 = 47928
- 109 + 47819 = 47928
- 131 + 47797 = 47928
- 137 + 47791 = 47928
Showing the first eight; more decompositions exist.
