Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23218, here are decompositions:
- 17 + 23201 = 23218
- 29 + 23189 = 23218
- 59 + 23159 = 23218
- 101 + 23117 = 23218
- 131 + 23087 = 23218
- 137 + 23081 = 23218
- 179 + 23039 = 23218
- 191 + 23027 = 23218
Showing the first eight; more decompositions exist.
