Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189658, here are decompositions:
- 5 + 189653 = 189658
- 41 + 189617 = 189658
- 59 + 189599 = 189658
- 149 + 189509 = 189658
- 167 + 189491 = 189658
- 179 + 189479 = 189658
- 191 + 189467 = 189658
- 251 + 189407 = 189658
Showing the first eight; more decompositions exist.
