Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72196, here are decompositions:
- 23 + 72173 = 72196
- 29 + 72167 = 72196
- 107 + 72089 = 72196
- 149 + 72047 = 72196
- 197 + 71999 = 72196
- 233 + 71963 = 72196
- 263 + 71933 = 72196
- 317 + 71879 = 72196
Showing the first eight; more decompositions exist.
