Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189284, here are decompositions:
- 13 + 189271 = 189284
- 31 + 189253 = 189284
- 61 + 189223 = 189284
- 97 + 189187 = 189284
- 157 + 189127 = 189284
- 223 + 189061 = 189284
- 241 + 189043 = 189284
- 331 + 188953 = 189284
Showing the first eight; more decompositions exist.
