Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49894, here are decompositions:
- 3 + 49891 = 49894
- 17 + 49877 = 49894
- 23 + 49871 = 49894
- 41 + 49853 = 49894
- 71 + 49823 = 49894
- 83 + 49811 = 49894
- 107 + 49787 = 49894
- 137 + 49757 = 49894
Showing the first eight; more decompositions exist.
