Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21196, here are decompositions:
- 3 + 21193 = 21196
- 5 + 21191 = 21196
- 17 + 21179 = 21196
- 47 + 21149 = 21196
- 53 + 21143 = 21196
- 89 + 21107 = 21196
- 107 + 21089 = 21196
- 137 + 21059 = 21196
Showing the first eight; more decompositions exist.
