Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189192, here are decompositions:
- 5 + 189187 = 189192
- 23 + 189169 = 189192
- 41 + 189151 = 189192
- 43 + 189149 = 189192
- 53 + 189139 = 189192
- 131 + 189061 = 189192
- 149 + 189043 = 189192
- 151 + 189041 = 189192
Showing the first eight; more decompositions exist.
