Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189216, here are decompositions:
- 17 + 189199 = 189216
- 29 + 189187 = 189216
- 47 + 189169 = 189216
- 67 + 189149 = 189216
- 89 + 189127 = 189216
- 149 + 189067 = 189216
- 173 + 189043 = 189216
- 197 + 189019 = 189216
Showing the first eight; more decompositions exist.
