Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23212, here are decompositions:
- 3 + 23209 = 23212
- 11 + 23201 = 23212
- 23 + 23189 = 23212
- 53 + 23159 = 23212
- 113 + 23099 = 23212
- 131 + 23081 = 23212
- 149 + 23063 = 23212
- 173 + 23039 = 23212
Showing the first eight; more decompositions exist.
