Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47918, here are decompositions:
- 7 + 47911 = 47918
- 37 + 47881 = 47918
- 61 + 47857 = 47918
- 109 + 47809 = 47918
- 127 + 47791 = 47918
- 139 + 47779 = 47918
- 181 + 47737 = 47918
- 337 + 47581 = 47918
Showing the first eight; more decompositions exist.
