Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18196, here are decompositions:
- 5 + 18191 = 18196
- 47 + 18149 = 18196
- 53 + 18143 = 18196
- 107 + 18089 = 18196
- 137 + 18059 = 18196
- 149 + 18047 = 18196
- 239 + 17957 = 18196
- 257 + 17939 = 18196
Showing the first eight; more decompositions exist.
